* CSS Sprites are unweildy. I believe there are a few tools out there to make this easier, but nothing seems to make it dead simple. * Support: when a user has a problem I have to ask them for their browser, OS, etc. There are a few sites that I can send them to, but it would be nice if I could send them to a URL that automatically emailed me their info. Or, it would be nice if I put a js script in the page that recorded that info automatically for signed-in users. * Design consistency: Sometimes it's hard to know if a change I'm making in the CSS affects other pages or views. It would be nice to be able to get screenshots of every page on my site after I make a change just to be able to double check it all. * Textmate bundles: There a bunch Textmate bundles that do the same thing. It would be nice if there was a site that 1) kept track of the different bundles from different locations 2) let people vote & comment on them 3) made it even easier to install bundles you see 4) made it easy to keep your bundles up-to-date. * Support: Often times users make a support ticket and the solution is for them to turn on cookies, or enable SSL or something. Every browser is different, and looking up this info can be a pain. What if you could send your users to automatic-support.com/turn-on-cookies, and the site would detect their browser and show them the correct instructions. This could be a wiki-like site, so other people could update the insructions. * Avatars/profile pictures: I'm tired of re-implementing user avatars. Gravatar is great, but it's too complicated for most of my users. It would be great if there was a service that let the users upload avatars, maybe make new profile pictures from their webcam, and provided some nice default avatars (like Yahoo does). If all that could happen without people having to leave my site, that would be awesome. * I've done a few sites where people upload and share documents and stuff. It would be awesome if there was a service that could give me thumbnail views of word docs, excel docs, pdfs, and other formats.
