The pop-up window is extremely small and nearly useless
I have a 14" 2560x1440 display and I cannot use the pop-up at all, it's so tiny.
Its dimensions are 195x126 which is literally just 3x2cm on my screen.
You really could make it a LOT bigger, at the very least 2-3 times bigger or at least add it as an option.
My DPI is set to 120 and the applet doesn't seem to care, if anything it takes higher DPI as a hint to ... shrink.
I'm using fully updated Fedora 38, so, basically the latest available everything.
If I start playback in applications with sufficiently long text in the title bar, the problems gets less pronounced, check #100 (closed)
