Usability speed regression due to submenus

While submenus can be useful for categorization, they often impede speed of an action that otherwise can be provided by something else.

The change to the modifiers menu is a key & critical example of a reduction in use speed.

This is the 'old' style of modifier add menu. As highlighted, from anywhere, any menu item is at maximum two main mouse moves and two clicks away. (calling the menu via hotkey reduces this to 1 for both of them)

This is the 'new' menu. With the exception of Geometry Nodes, all modifier items are now 3 movements and 3 clicks away.

There is also another thing that the 'old' layout can do, that the new one cannot. Menus in blender close when the mouse is moved off them (expected & intended behaviour), and because the 'old' layout is effectively all these new submenus stacked next to each other in a single element, moving from Generate to Deform is a single motion. Compare to the 'new' layout where moving from Generate requires a movement & stop onto the root menu, and a second movement & stop into Deform.

I've always found blender's ability to stay out of my way and let me get directly to what I want to be one of its biggest strengths. This gradual introduction of submenus all over the place is making the program slower and more cumbersome to use. There's a reason that an addon was made to revert the modifier menu to the flat show-everything style: It's simply faster to use. This isn't just about the modifiers menu, it's about the slow creep of deep submenus everywhere.

Don't shove everything into as many submenus as you can think of, it's annoying and slow.
