@silentheart00 It is already there! Bullet point 9 in the User Interface section. 🙂
And you’re right on – I love it as well. It was always a little awkward having to middle-mouse-drag on those icons to scroll through them horizontally; hardly anything else in Blender’s interface really worked that way. Just like you I always felt like I had to widen the panel more than it needed to be, for that reason. The way it is now, usually my Properties window is tall enough that I don’t even have to scroll to see all the icons. It just seems way better to me. By the way – by right-clicking on the icon list you can swap it to the right side of the panel instead of the left side, if you’re so inclined.
I was surprised on the dev forums to see some opposition to the vertical tabs….but it wasn’t much opposition, and anyway I suppose there’s going to be at least someone upset with any given change.
