Great app... I've been using it since I switched to Linux years ago.
I have a couple of suggestions/requests that I think could improve it.
How hard would it be to convert the pad to use HTML? A lot of what I use xpad for is scraps of webpages I need to get back to (and don't really want to lose the page in my bookmarks). So, I'll throw a UPS package tracking number in xpad. But, what I'd love to have is the actual link to the tracking page. Or, I'm considering buying a new webcam, and I found a great price online. So, I'd love to keep that link handy until I'm ready to buy.
I figured that this would only be an extension of the bold/italics/underline formatting. Plus, I have a little experience coding C/C++, so if you'd be willing to point out what changes you think this would require, I'd be willing to give it a shot.
Thanks.
Rather than supporting html, maybe it would be enough/better to just make any links clickable.
