If you could allow the user to specify the command char, it would be awesome. Great work, though!
2. Searching google and other search engines without going through yubnub command (eliminate the extra HTTP get). I know i can search google through the address bar and the search box on top right, typing 'g' is much easier than command+L and command+K.
3. ability to pin/unpin the gleebox so it does not disappear despite http refresh when I open a link in the same tab.
For #3, we experimented with a hyperglee mode. In that mode, gleeBox shows up automatically when you open a page. It actually exists but is an undocumented feature (since we weren't completely satisfied with the results) :)
In Chrome, you can turn the hyper mode on/off by executing '!set hyper=on/off'. Doesn't work too well in Firefox, though.
lo::facebook (could use your save username/password in firefox) or lo:facebook -u username -p password
Since many a times the login page on websites is uninteresting
And, with gleeBox, you can do a lot more like search bookmarks, execute bookmarklets, yubnub commands, etc. Plus, I think it is more easy to use for the non-vim junkies :)
Hints allow you to select a link, either by numbers assigned to each link in your current page view, or by typing the link's name.
Maybe I misunderstood the way gleeBox works, but from what I've tested, you can select all links (with ?a) but you then have to navigate to the correct one by repeatedly pressing TAB? That's a show stopper for me.
But like I said, kudos for the initiative.
On a related note there's a standalone browser with vimperator-like features currently under developpment although the available versions are more than usable: http://www.uzbl.org . When it gets stable, I'll definitely dump firefox/vimperator :)
So, you can simply enter a part of the text of the link you want to go to. If multiple links have the same text, you can TAB your way to the right link. You don't need to use ?a.
#2 - Makes sense.
Feel free to ignore these suggestions if you think it will affect usability and bring more complexity.
I support anybody who tries to make me use my mouse less, and the browser is the biggest pain point right now in that arena :)
Maybe someday... :)
