Hey there. I like the application. It works smoothly, does what it needs to do, isn’t overloaded with useless features and is generally very useful. One small remark, is that I’d like to see a better way of distributing your application for linux distros other than debian based ones. I have two suggestions that should be rather painless for both the user and the developers.
An appimage is basically a portable executable that can be executed on all distros, without any dependency problems. Drop the appimage anywhere in your filesystem, double click and the application starts.
Flatpak is a cross-distro package manager that allows developers to package the application and its dependencies and distribute the application to any linux system. Again, without any dependency problems for the user. It works pretty much like an appstore. The advantages of this, is that your application will be much easier to find for linux users. Many of them would be able to download your application straight from their application store, integrated into their distros and desktop environments. The trade-off, is that its slightly less convenient for the developer, although it still shouldn’t be very hard.
