I have been doing a lot of work on the core files to enable them to support as many cpus as possible. Some of my changes have already been accepted for version 20. I hope some more of them will be as well. Here is a list of what I have working.
I'd like to see more in the IDE. I've wondered why the more common and stable playground libraries haven't been included and the extra board/chip definitions (as mentioned earlier). Maybe those could be under some "contrib" type menu? Or is this a taboo subject? (remember I'm kinda new here)
