1. Not a file - but perhaps in the app itself, before exporting it, it'll show you the H frames and V frames - for example in Godot, when importing a sheet we have to specify how many rows and columns it has so they are aligned.
2. To add to that - having a 'lock' button next to each feature would be a nice addition, so if for example you want to lock down a specific item (race, color, beard..) you could do that without randomizing everything.
Thanks again!
