Please double your prices, at minimum. (And port to Linux, so I can use it. Just CLI would be great.)

Making this cross-platform is definitely a goal I wanna work on, but I lack knowledge of desktop app development on Windows and Linux.

I'm glad you think the app is cheap. Honestly I think the pricing is decent for the current set of features. I might revisit the price if I sneak in more features worthy of a higher price tag, but for now, it's good enough.
