There's no support for Rumble's Framework anymore. At least not this one, and its bulky/slow (used it myself for a while and it was a great ride). StarMan's MPB is much lighter/faster with all the same functions plus more (with minor changes in how you use the tokens) with great support....
Thanks Slayve2DnD, a couple points...
1) Rumble does answer questions regarding his FW, but you are right, he is personally not providing fixes anymore... Others have though. When required I send Rumble a PM. He has answered everyone I have ever sent.
As for the slowness you speak, there can be a lot of causes for that, not all the FW's issue. My group keeps token graphics quite small, and thus have avoided most performance issues that would cause us to want to switch.
2) I am aware of StarMan's FW. There have been a number of post in this thread about it. Frankly, they are off topic for this thread... I hope this is the last one I need to read.
In summary, Rumble's FW has everything I need to run a successful 4e session, my player's like and know it well. We have been using a very long time. Changing now is not in the cards...
...but thanks for the sales job.
I may look again to StarMan's work if he works on a D&D Next FW. Hopefully, lots of people unite to build a great one that is both fast and easy for us non-coders. I'll look for that thread when the time comes. Info on it need not be posted here.
