If you build it then I won't have to.
1. Hacker News Clone in PHP that can be easily integrated with wordpress/buddypress through a plugin.
2. Good event management plugin for wordpress/buddypress
Apart from that I have some other ideas too:
1. Draw&Share Mobile App - let users draw freehand drawing using touch screen and share it with friends(on facebook, mms, etc)
2. Collaborative Whiteboard Web App - A simple whiteboard(freehand drawing + image/text/video/audio embedd) + Chat(text/audio/video)
3. UI Library that uses HTML 5 canvas instead of normal html/css/js controls.
I'd especially like one that suggests hyperlinks for documents based off of what users typically make hyperlinks for or based off of some kind of algorithm with heuristics built on content and formatting conventions, because even though just being able to create your own hyperlinks would be handy for studying and reviewing, having them appear magically would be a killer feature.
However, that'd probably be too hard for a single weekend. For one thing, it'd still have to be a good PDF viewer, which means nice features like being able to custom crop/zoom pages to hide margins in documents with lots of extra white space, and it'd have to perform well with the large, complex kind of documents that people would want to add hyperlinks to.
It also lacks long term viability due to the slow rise of eBooks with hyperlinked content on delivery platforms like the Kindle.
I know there is the Windows Workflow Foundation, but I want something which doesn't necessarily have to be compiled, but that I can translate user input directly into a new rule set.
Basically, a definition-fetching app that stores the definitions in a clean and aesthetic manner.
I tried making this as my first web app using the Google Dictionary API, but they disabled it just as I had something going in Flask. I keep trying to get back to making it but I've got so much to learn. Maybe I should just...... FIND A WAY. OR MAKE ONE???
I'd use it everyday, especially if it was a browser addon :)
(P.S. My preferred platform is Android, but I'd love to see someone attempt this on anything!)
I'm being serious here, by the way. Double-click on your notes file to open. Hit <Enter> twice to start a new note. It has all the features you mentioned (except for the Android compatibility). Are there others you want?
Portability is achieved with a notebook and pen.
Briefly, it's a unique spin on tracking workout progress. I'm not sure how well I explain it in my post but, most of the ground work is done already so an MVP can probably be built in a weekend.
