Just an idea... if you are viewing something, have a browser extension to take a screenshot and then be able to post it to a topic without leaving the page. A simple drop-down menu to select what forum/topic or create a new one with a comment as an option.
@19eighties Firefox > Screengrab. Allows me to do this without leaving the page. 
Just requires clicking Save in right click, then upload to imgur through the composer.
@a_5mith What if you're grabbing on another site? Then you have to go to another tab or open one to the forum and get to the topic.
Didn't think about that bit, but seems a very niche request. And probably better suited as a plugin. 
@a_5mith Agreed, just an idea... it'd be a way to share any content a little more easily without leaving where you are at.
On windows you can use ALT + printscreen to grab a screenshot of the current active window then paste that into the composer as well.
Windows also comes with a really cool "Snipping Tool", iirc.
possible with canvas I think, so no ie8 support
I use Sharex 
It allows me to grab a region, upload to my server and copy the link, all in one button.
@xbenjii That tool sounds handy.
Just wondering if anyone else would find if useful to upload directly to a post with a capture tool. I find it better to just give an audience an immediate visual instead of (or as a supplement to) a link since it breaks the flow and many may not actually click the link. Sort of like being able to reply to a post via email direct.
