Here's an item that bugs me a lot, and there is probably not any solution, but just maybe...
Often I'm editing text in a textarea on a web page, and I'd like to edit it in my Favorite Real Editor. Of course I can select all, copy, go to editor, open new, paste, edit, select all, copy, find browser window, select all in the textarea, paste.
Is there a way to make this easier? Like hit a key and the editor opens a window with the text. When I close (and save) the results are returned to my browser window, and so am I.
I suppose there might be some hack where I could select text, hit a keystroke (or something) and have the select text appear in the editor, then if the default were to select all+copy when closing the window, ...
Anyway, some better solution to this problem would be really great.
A specialized hack might be to have the txmt: protocol thing integrated so that the editor could fetch text via HTTP and know where to POST the text upon completion of the edit. This may be a complete waste of development effort since webdav is the right and proper solution here. (By the way, I haven't used webdav to any extent really.)
This whole thought-stream was launched when I started looking at wikis again. I love the ease-of-use of wikis, EXCEPT for editing in HTML textarea blocks.
