However, exophase will do whatever he wants regardless.
True, and we shouldn't go around walking on eggshells, but a consideration to his wishes regarding the beta certainly doesn't seem inappropriate.
No additional work has been done on the Pi version of DraStic since the Beta as far as I know.
That's tough to gauge. He maintains that his work there will resume when he gets time. Plus, we really don't know what's been done so far. DraStic is normally paid software on most platforms and I'm sure they get a higher priority.
Anyone been in contact with him?
He's remained quiet. There are a few others that have commented on the issue here as well.
