So b25 has a few improvements that will hopefully make DubScript work better with other applications. DubScript better registers its supported file types with Android, so now if someone emails you a "fountain" or "trelby" script, Gmail should recognize DubScript knows what to do with it and allow you to save the file and then view it.
Unfortunately, I haven't yet figured out how to make it handle the "view" option in Gmail without the file being saved locally first. This is due to the fact that DubScript supports at least four formats, and I haven't worked in a way to automatically detect the right one. (Normally, I use the file extension to make that determination. Does anyone know if I can make "intents" include the filename along with its contents? If so, let me know below.)
Anyway, that plus some minor tweaks and text changes are all that's new in this version. But if you're using fountain or trelby files, it should be way better.
