There's options to "save current settings" and "save settings on exit" in the file menu. Saving the current settings after you save a skin will give you the same settings you had the next time you start the app.
For next version though I'll add in an "open" feature. It'll work a little differently though since the program can't actually read a finished skin (it just reads the "style" format I came up with). It'll save a "Skin Name.skin" in the folder you run it from so you can load up all backgrounds and settings just like they were when you created it.
I'm glad you find it useful, and thanks in advance for any donations
(It'll actually be my first)
Edit: Donation recieved
Thank you so much.
I'm putting that towards getting a server I can log into more than 50% of the time, hehe.
