This is an excellent new function which I have been waiting for for ages. Three things:
1. To control the speed of playback you have to press ALT + RIGHT / LEFT or CTRL + RIGHT / LEFT – this is fine when using Kodi on Windows but when using via Kodi Remote Keyboard (official app in Apple Store) there is no option for using either ALT or CTRL so this cannot be used as far as I can see. Similar for those using an Android Box I would imagine…
2. This works fine on Estuary (Kodi default skin for Krypton) but when used on Confluence the GUI menu fails to disappear after the default amount of seconds.
3. When you pause the video (playing at 1.2x for example), it begins again at normal speed (1x) upon resumption.
