Honestly, yours looks even snappier than what I had, the way it’s handling zoom feels super fluid. Really impressive work! Makes me want to dig back in and see if I can match that speed.
My code runs natively, so users need to download a client and I have to code the rest of the ui in cpp, that’s the downside. I did consider a hybrid approach with Electron or Tauri, but dropped the idea to avoid IPC overhead and get the best possible performance.
For example, I don't even own a windows pc.
From what I understand there are two good FOSS PDF applications for Windows. The platform that is in need of a good PDF application, where you'll acquire users, isn't Windows.
