But this ugly popup on closing of qjackctl window is a bit annoying. My final goal was to get it with option like "Don't remind anymore", but even getting messages appeared not very easy.

I use sometimes qjackctl to control transport during work in qtractor, because when in qtractor i open track properties to test various plugins, all other gui is unavailable, excepting only plugins gui. But this ugly popup on closing of qjackctl window is a bit annoying. My final goal was to get it with option like "Don't remind anymore", but even getting messages appeared not very easy. My implementation uses notify-send utility, which in ubuntu is packaged in libnotify-bin package. Arch wiki says, that libnotify is good for both gnome and qt4 apps, but it seems, but basic libnotify api, written on C, is glib/gobject-based, and i can't find libnotifymm (same glib, but on c++) in neither ubuntu nor portage. Though in gentoo i found even some kde stuff, using libnotify %).
