I don't understand why they chose ImGui. As it is immediate mode framework, it means it repaints whole window for every incoming event, like pointer motion? Ridiculously inefficient.

Also I don't think it is safe to add third-party repositories as they suggest to do for Linux users. I never do this.

The app is meant to run in the background or minimized once you've edited your Midi profile. Your rendering costs are zero.

The app will eventually be packaged as a flatpak and submitted to flathub in the near future.
