Well now that is really nice. TwBlue's latest version is getting to be a nice alternative to tweesecake. You can now get to filter posts, you can now specify the language in which a post is written... Definitely looking like a suitable alternative, more and more.
Now, if only one could make it so the enter key does not post but rather make a new line, and to send with something like shift+enter or ctrl+enter, that'd be perfect. I will have one hell of a hard time to adjust.
