I can create an "Upload to OpenProcessing" plug-in for Processing. It would be a menu item under Tools menu in Processing, which would automatically Export your sketch, .zip it, and upload it to your account, and show you your sketch in your browser.

"Tweak the sketch" feature would allow anyone to edit the source code of anyone's sketch live on the website, compile and see the result on the fly, and post it back as a response. See opencode.media.mit.edu, they have a similar backend that allows live editing.

many people use no or bad tags on their sketches, it would be great to be able to improve on that by adding your own tags to other peoples sketches

A way to track 'parentage' of a sketch, when a sketch is derived from another on the site. Implementation: include a manifest with the sketch's id when downloading a zip. This information is passed back to openprocessing when the child sketch is uploaded. Inspiration: MIT Scratch.

If the user puts a "thumbnail.png" or "thumbnail.jpg" file in the archive, this image is automaticaly used as the app's thumb image

A copy/paste code widget that would display a list of user's sketches (thumbnails) in any webpage/blog.

1) Allowing link for a OpenProcessing sketch that may look like that:
[link:123]the name of the sketch[/link] where 123 is the visualID of the sketch.
2) Allowing external link like [url=http://en.wikipedia.org/wiki/Mandelbrot_set]the famous Mandelbrot set[/url].
3) And a link to the portfolio of the user who is commenting (by clicing on his logging name under 'comments'.

Would be useful to have the thumbnails expand (or show up in the 'featured' window) in the openprocessing homepage when rollingover with the mouse.

- disable saveframes() before uploading
- ...
beginrecord (for pdf) seems to break the applet rendering too

When I follow a code creator I'd like to find easely his work

It would be nice to subscribe to members, so we know when new sketches are uploaded from them.

We need an IRC channel or chatroom of some sort to collaborate ideas and feedback live to eachother.

Something like FlickrRSS or VimeoRSS.

The main page still no official icon

It looks like links do double duty - as normal href's and by changing the page via javascript. So if you "middle click" to open in new tab, the link opens in both the new tab and in the current tab...

beside the sketch thumbnail (but without opening it) it would be nice to have an idea of the number of comments that have been written (and even something like a "new" label when the last comment is fresh)

Change the way tags are displayed when browsing by tag. There are so many tags now that you can't read most of them since they're so small.

Java loading is a slow task that stops the browser, so it's hard to browse new contributions and get a bit frustrating!

For VJs or Resolume users it would be fantastic to have a release of footages from openprocessing sketches.
The author of the sketch must be agree with this.

would be great to jump quickly between app, users blogs, external websites suggested in comments.
