Move Applications between Categories in App Launchers

One thing I find difficult in the Application Menu and other launchers is that the applications are in categories where they are not always easy to find. like “Network Settings” is the category “System Tools”, sub-category “Preferences”.

I tried moving apps to personalized categories with Alacarte, what was was a really tedious procedure, because you have to click a thousand times, only to see on the next login the apps had miraculously moved themselves back to their original category, so I gave up on that.

I would like to be able to move the apps easily around between categories, like a sort of drag-and-drop function, and maybe even be able to create new folders or rename, or hide existing ones, right from inside the launcher.
