Open With > Other Application

When I right click on a folder in Dolphin, and select "Open With", I want it to list both VLC (my video player) and Audacious (my audio player). These applications are both capable of opening folders and recursively queuing up all files within that they are capable of playing.

Since they're not listed by default, I then select "Other Application" from the "Open With" sub-menu, which gives me these options (link to screenshot below):

This does indeed allow me to ultimately open the folder (with my application of choice), but it doesn't put that application into the "Open With" context menu (so that the next time I right-click a folder, I can more quickly open with that preferred program without having to navigate through the application-hierarchy showcased in the screenshot linked above).

Even if you foolishly disagree that this "Open With" context menu shouldn't automatically grow each time I "open a file/folder-type with a different application", you'll have to admit that the best place to add things to this context-menu is on the "Other Application" dialog that I've screenshot-linked above.

The "Remember application association for all files of type" checkbox should probably not even be available for folders, but even if you decide to include it, it doesn't address the option of adding things to that context menu.

I'm sure there is another way to add things into that context menu, but I'm a big proponent (in UI design) of placing features and settings "where they are used" and not in some separate place that isn't "right there" when I'm wanting to do the task.

So, I propose that you either add things to this context menu automatically (each time the user opens with a different application), or instead add an additional option to the "right-click-file-OR-folder > Open With > Other Application" menu that allows the user to explicitly add it (the very first time they're burdened with navigating that application-hierarchy showcased in the screenshot linked above).
