I believe Leo could benefit from having the "go anywhere" feaure from sublime text. It's activated by ctrl+p, after which you just start typing.
In the "video" on this website, slides 4 and 5 show it in action:
In leo, stuff you could type there:
- Headline snippets
- File names
- @function names
- #words in current node (or whole leo file?)
It's important that the number of hits is rapidly narrowed down as you type more text into the search.
I used this kind of feature a lot in Qt creator, and can testify it's an order of magnitude faster than using a mouse (first requires searching for a while from a long list, in case of leo probably scrolling around, expanding nodes since the node being sought is not visible in the viewport...)
