Never got to try out PhotoSuite, looks like it really was just ripping-off your code, the repo owner already deleted it, and now it forks PhotoCraft.
I have a huge respect for your work on Photopea, been using it constantly since the time I completely moved to Linux a year ago. It has the best Photoshop parity yet to find! Would you ever consider to: 1. Open sourcing your work (partially or completely) under some kind of a permissive/copyleft license. 2. Rewriting some parts of the website that require performance as WASM targets. 3. Using any modern JS frameworks, e.g. Svelte.
