What are the limitations of an unactivated Pyxel Edit?

Question

Design

Program version - Pyxel Edit 0.4.8 (current).
I launch the program - a pop-up window shows two buttons: "Activate" and "Later".

I choose "Later". And so every time at every start.
So far, I have no complaints about the work of the program.
But maybe some functionality has been cut? The program is paid. Could not find information
on the official website .

Pyxel Edit is currently in development and is available as a beta version at a reduced price to support development. Then the price gradually increases with newer versions. Buying the beta will now give you all software updates for free, so get it while it's cheaper!
9 bucks - well, if the program is already normal, you can support it
