I wish I could say this is my idea, but it's originally coming from YouTube Music, which I've been enjoying lately.
YTM similarly to YT has this feature where you can double tap on the left side of the track, to Rewind, or you double tap on the right side of the cover, to Fast-forward the track.
I recorded the feature for you:
Additonally you can choose how many seconds the double tap works with. Currently I have chosen 10 secs, which means if I double tap left or right, the track only Rewinds 10 secs back, or Fast-forwards 10 secs.
This can be chosen individually.
I would love to see this feature adopted by Deezer 
Following screenshot shows YTM settings for that feature.
That's a great feature
Can a mod please adjust my post.
"tap on the left side of the cover, to Rewind, or you double tap on the right side of the cover, to Fast-forward the track"
First two mentions of track should be changed with "cover". Because you tap on the cover.
Sounds good to me too
