I have done zero investigation into the API (I’m assuming here) for the EFB.
In poking around with Navigraph’s 2024 suite it is exciting to see their features implemented as EFB “apps”. That is pretty cool and would seem to lend itself to what you’ve suggested as a path towards customization implementation.
Obviously, we are in the early infancy (some may argue embryonic…) of 2024 and have yet to see what can really be done here.
A step backwards is that the UI can’t be scaled down. It feels like 1995 again when I was playing in 640x480, because the UI elements are so big.
MSFS 2020 feels so fresh when going back, playing in 4K with UI elements scaled all the way down 
Here’s another QoL improvement I’d overlooked.
My library has the ability to toggle on/off content.
In 2020, I’ve gone to the trouble of categorizing my OneStore and Community folder content with colored folder icons. I’d move content by hand to a storage folder to disable them, as needed. I never bothered with add-on linker or whatever it is called. I didn’t want one more program involved in my installation.
Anyhow, what is really great in 2024 is the ability to toggle them on/off via My library. This ability includes WUs/CUs and other base sim content that I always found too difficult to identify for my colored folder icon method.
Using the filters, you can identify Community folder content instantly and disable/enable it easily.
Here’s one of those steps backwards in QoL from 2020-to-2024 that needs to be made right:
Yeah, I don’t use ATC because it’s a distraction from trying to fly, but I have to in Career, so I was reminded of this right away. No problem, I thought. I’ll just pop out the ATC window and move it monitor 2, expanding it so it shows everything. Nope, all that did was horribly distort the window.
I would go as far as saying I think there are actually a regression compared to fs20. As a whole the complete experience feels more confusing and difficult to learn/use. To me, as a user, that is what matters if you are talking about QoL. I still can not believe someone designed that UI and thought it was even remotely decent.
To me the overall userfriendliness is a step backwards from fs20.
I dont think all the current small bugs and annoyances on top of it all helps either.
On the positive side, I really like the concept of bringing in the EFB. Thats the one big thing that sticks out to me as really positive. I dont know if you can import directly from simbrief or similar to it, but that would be one example of a great quality of life improvement, to me.
It seems MS/Asobo pretty much threw out the baby with the bath water in moving to MSFS 2024. They felt they needed to slim down the client side as it had grown to use too much disk space and this was not feasible going forward.
One step forward, 8 steps backward.
You are luck, anytime when I try open any window (ATC, EFB), in separate window for to move to other monitor the GAME crash 
Another QoL improvement I’d overlooked is the Red IFR & Green VFR dot when clicking an airport or selecting a parking spot/gate.
Unfortunately, due to some wackiness with the UI/weather it’s a bit bugged:
In fairness, that can be said about just about every copilot I have ever flown with IRL. One of the few things Asobo got right in 2024.
I don’t think there is much surprise in them not implementing a personal wishlist of one user. They cannot read your minds. MSFS has had a wishlist voting for years, that is the only things they can and should go by. I think it is extremely unfair to expect them to have done what you personally want.
Most of the items on the list are already in the Wishlist.
Where can I vote for the world map filter saving? The rest I honestly do not agree with you.
I don’t care if you don’t agree with me, I’m not here soliciting your opinion.
Voted, thanks. It is a good suggestion among others that have received a lot of votes. And since they have, they will receive deserved attention form the devs, we have seen it during the last 4 years of 2020.
Hmm… the wishlist item you just voted on was started in September of 2020.
That isn’t what I would call deserved attention.
Excellent post Nixon. I agree (for reasons laid out in the following thread). Unfortunately, a number of these have carried over into MSFS 2024.
From May of 2022, some thoughts on the topic:
An important post from that thread:
Note that there is a typo- the tag is ui, not ux as written.
Yes, deserved. Or are you implying they have done no improvements based on the wishlist at all? Have you watched any of their dev streams, where they go through the most voted items on the bug and wishlists and comment on them?
You’re looking for a fight I’m uninterested in engaging in.
Reread this thread.
Did I state they have done nothing?
If the QoL items that I outlined, which are wishlist items and some of which are as old as 2020 itself, were reviewed prior to developing 2024 they could have easily implemented changes at that time.
That is what a good software producer does — spends time with the product, reviews the bug list, reviews community requests — and looks to incorporate improvements like these in future versions of the software. I know this, because it was my job.
If you disagree with that methodology, that’s totally cool, but don’t misconstrue my words to suit your agenda.
