Hello rern,
I'm annoyed from "Replace current playlist?", too. So I added "//" in front of line 69-73 and 75-76 in enhancecontext.js
Because of sometimes accidentally swiping to library on sliding the time knob, I disabled swiping (line 292-294 in enhance.js), too.
(In my opinion, swiping on an 10" Tablet is not necessary; bottom-buttons are big enough).
-> Much more fun
Please make both functions optionally.
EDIT: complete disable swiping is no good idea - tablets work great, but smaller displays like my Moto G4 play shows no bottom buttons. Navigation is impossible without swipe. It should depend on visible buttons.
Another (less annoying) thing - The back-button on library should be on the left side, like most other web-browsers. I would prefer them between library-icon and the current path.
Regards, Andy
