In Blender, there are several menus that allow you to add/removed items from it.
For each of these menus, we currently place a + and an x button next to it to add or remove items from the menu.
The problem with this is that it adds considerable clutter in the UI. While a menu is conceptually one thing, the + and x makes it seem like many things. Was this only in one menu it could be ok, but these menus appear many places throughout the UI, and the net effect is loads of these tiny + and x buttons. Also, when hitting the X, it's not so clear that the item is removed, because you have no overview of the list when hitting the X.
Move + and x buttons inside the menus.
- Much less clutter throughout the UI
- Saves space
- It's faster to delete specific items, because you don't need to switch to it first
- It's clearer that the + buttons adds a new item, because you can see it immediately in the list
- Removing items is also clearer. When hitting the X inside the menu, you see the item being removed from the list
To clarify the effect of hitting the plus or minus icons, we could add colours on rollover, like so:
