Kate's quick document switcher is excellent for quickly switching to a document by a part of its name, and I use it often. But even more often I find myself wanting to use what is often accessible in other editors via CTRL+TAB and CTRL+SHIFT+TAB: a way to cycle through the currently open documents in order of most recently viewed.
This is basically analogous to the window manager's ALT+TAB mechanism, and often involves a popup window showing the files in that order with the currently selected one being updated as the user continues to press the keyboard combination.
Just found an earlier bug for this problem.
