Bloody Paint Tool Sai (Small Vent Rant)

has anyone noticed the lack of ways to convert a .SAI file to something like a .PSD or .MDP or be able to open it in other programs? No? Just me? Well!

I have started to become increasingly annoyed with trying to find a way to use free bases because so many good artists use P2U art programs... (Like Sai) it doesn't help they have their own format which makes their base art files incompatible with mainly all other image editors...

 

I is a very annoyed Wuff Wuff...
