Hi there, I'm glad you like it! And apologies for the delay in responding; life, etc. Development is slowly continuing. I've had to take a break over the summer to work elsewhere, but I do have a roadmap for things I'd like to add and improve. I have plans to add more content in the future. In terms of features, it's mostly done as is. I do have a laundry list of things to fix, and I would like to make a paid version which will only differ in that it'll have extra, ancillary features; nothing that wouldn't be missed from the current free version.
