I can see you've been making notes of a lot of the things that many of us have struggled with or found unfair - a lot of these things are failures of the game's control system and UI, but a lot of it is mechanical as well. There are quite a few threads that deal with these problems in depth, but I would very much like to encourage you to submit your personal dissatisfactions through to Larian directly, using their formal feedback and bugreporting forms - that way you can be certian that your voice will be heard.
Larian said they read the Feedback Forums so it is not wrong to post it here. Sometimes something you think being wrong is caused by own failure, sometimes it is a bug. Sometimes it is something that if removed or changed the wrong way would severely impact balance. It is good to show these issues to the player community as well. They can add additional ideas and feedback.
For the most part I have seen, Larian wants to take the stuff that made DOS1 and 2 special (surface, crafting,items, throwing stuff, positioning, shoving...) and don't have the experience with DnD5e to see what it does to game that uses this rules as its core foundation. Crafting isn't in game yet but you can expect it to break more than just a few things as well. => In this cases it is good to collect a bunch of ideas because it is not easy to find a good solution to not entirely remove such a system but still keep balance.
As for the UI and cotnrol stuff => These are mostly bugs easy to identify. But again easy identifyable doesn't mean easy fixable. A potential fix could cause issues at another location.
