Devs do read the forums, but very rarely respond. The best way to get these bugs raised and captured is via the formal bug reporting through zendesk - click the “support” link at the top of the forum pages. There is also a bugs/issues section of the forum, where you can create topics for these bugs that allow people with similar issues to share their experiences and vote on them to raise visibility.
Note that forum rules require one bug per topic (so you’ll need a few topics). However, I suspect you’ll find that these issues are mostly not xbox specific and so someone will almost certainly already have created a topic for these already and so you can add to that and vote too. Try to avoid duplicate topics because then the votes get split. The search function in the forum is very good.
For example, this thread exists for the toolbar handle not hiding:
