[FEATURE: QoL] Hijacking the right click in `playlists` menu

[crackheadakira]

Currently when right clicking a playlist it just shows the regular context menu, which probably wouldn't be desirable on the playlists folder, as many people are used to being able to right click on a playlist and quickly delete it or rename it from there instead of having to open it up.
So preventing the default interaction and showing your own context menu for playlists would be a nice QoL feature, this could also be made to scale so you could easily replace the default context menu when needed.
