A2 v.2.1.1 is in use.

1. Failed to make working these Player functions declared by Amarok in IRKick config wizard:

Player::VolumeUp
Player::VolumeDown

- both do nothing.

2. Have not found a function to seek +/- X seconds.

Have I missed something? Or - must I report a bug?

Well, also showOSD  function (or something like) seems to be missed: with lirc-oriented using of Amarok 1.x it was *very* handy to have this feature with remote control - to see with button push from a listening point  "who, what and how long".

OK, have filed https://bugs.kde.org/show_bug.cgi?id=203532
