Instead of cycling through loops and views with the arrows, I always seem to get lost, something that more closely follows scistudios navigation layout.
As far as reimporting the bmp, following the logic of some of the captcha image decoder bots that read the registration images, the cel boundaries and loops are already there, visually. We just need to "read" the boundaries of the background color, as it surrounds every cel we need. a loop is all on a horizontal plane so when there isn't a next bounded area, then it is the last cel. In my head it seems easy
But I'll leave you to dwell on that, but I'd much rather see bmps that were easily imported from the gallery than a proliferation of zip attatchments. Imagine Mt, considering so much code got buried in there, how much space would be taken up by resources that just get lost over time.
Maybe an option to save to bmp, or png. then we could upload the meta data'ed files here or use bmp, well since no one was sure how it even worked, I don't think anyone ever used the exported bmp's for anything. Easily importing image files of multiple loops and cels I think makes this a feature worth exploring regardless of scistudios support.
