Totally agree. The best use case here is hooking up your keyboard to a personal database to autocomplete notes you saved, like locations, bookmarks, and so on.

Totally agree. The best use case here is hooking up your keyboard to a personal database to autocomplete notes you saved, like locations, bookmarks, and so on. I have a note-taking system that I use to store all this data, and after I set it up years ago I looked at implementing an IME to search my notes and get a link to an entry, but every platform has its own byzantine IME API and I never got anything working. I've been thinking it might be easier to just make a cross-platform program that interacts with the clipboard rather than being a true IME. In general one effect I'd like to see from having flexible IMEs would be allowing logging and chat could be left to separate apps. Imagine a birdwatching (or whatever) keyboard that lets you pick the birds you saw, their age, behavior, and punch it in while you're in the field, and have it output in structured form into whatever app is handy.
