A little feedback on the UI…
As I think I understand it, the things circled in red are previous alphabets/schemes. And that if you want to change to that you press on it.
To me it is a bit confusing as it seems like it could be a heading since it is the same text size as the actual alphabet selected. It was more confusing when I had previously selected a similar Roman scheme.
Or when it says Auto-Detect in the drop down, as above… Is it auto detecting as Sinahla?
Personally I’m not sure how useful the feature of having the previous alphabet as button there is.
Just a thought. It really is an amazing tool. It’s clear you care a lot about the project.
