I'd like to have SFTP uploads in HotShots, I've always used SCP with Ksnapshot and it worked great, now I'm looking to move to HotShots.
Before you say it's a huge feature: it doesn't need to be. It's enough that you add scripting support - let user supply a bash script and call the script instead of uploading to FTP. I'm using that with ksnapshot now and it's reliable.
In a "luxry edition" of this feature request, you'd read output from the script and copy it to clipboard (so that the script can supply URL).
Also will be good to have ability to add any new http uploaders, for example add new public uploaders (wstaw.org, im9.eu, etc) or use local corporate uploader (on internal network), and change settings of already exist uploaders (if they will update protocol or change hostname).
