I have been looking for something exactly like your software for such an excruciatingly long time now! It really does exactly what is needed for world building. Thank you so much for this :)
One small thing, and maybe it's just me suffering from data loss, but it would be absolutely awesome if there was a shortcut to quickly save, simply overwriting the currently open file without a save dialog.
An optional autosave after Generate would of course be the cherry on top of the cupcake *haha*
Keep up the good work, you're always awesome *thumbs up*
