Agree with these suggestions-
Also linking another thread where this was previously brought up (unfortunately without any success)
I am not a blind user, and wanted to chime in to say I think this feature would benefit a greater percentage of users that solely blind users.
I find it very difficult to learn how to use an app when I am faced with a bunch of icons that I have no clue what they do. Yes, once a user is familiar with the icons- removing the labels makes the interface cleaner. A perfect example of why user-choice is very important.
In the early days of Obsidian, there would be far less interface icons to learn- Obsidian had less features and there were less Community Plugins. In this scenario label free icons make somewhat more sense. (Still prefer labels, but alas.) Today, Obsidian has so many fantastic features that using icons alone is not sufficient- labels should be added such that the user does not need to hover over every single icon just to learn what it does.
Looking forward to this UI improvement.
