JSONpad v2 is in progress! :D
So here is a short overview from the changes:
The most important change will be that finally the editor works in the browser and as air application from (mostly) the same code.
Another bigger step is that you can start the editor in multiple tabs. So now you can edit/view more than one JSON string at the same time ;D.
I also updated many stuff from 3rd party code like CodeMirror, Adobe® Air®, and more. Many things are faster now.
And maybe, but not for sure at the moment, i will include another design than the extJS default.
Oh yes and i forgot, JSONpad will become a GIThub project soon :)
Can't say exactly the time when i'll release it, but it should be this year!
