I recently retried using GwenViewer (KDE image viewer) for better integration with system and ability to copy image from right-click menu, but ultimately returned to imv (command-line or minimal wm oriented image viewer for Linux X11 and Wayland) because I already gotten used to it’s way of doing things

But also, I gotten to config and added keybind for changing upscaling method, because it’s a bother to type it every time I want to look at pixel art
