Phisical Button for REAL control of Deezer

I've been frustrated by one particular Deezer limitation for about ten years, and I think there is a relatively simple way to solve it. What I would really like Deezer to introduce is user-configurable global hotkeys on Windows for Favorite/Unfavorite and Don't Recommend.
The Windows app already has “L” for liking a track, but it only works while Deezer is the active window. That defeats much of the purpose of having a desktop application. If I'm working in Resolve, Photoshop, a browser or anything else, I should be able to assign my own global key to these Deezer actions and use it without bringing Deezer to the foreground. The important part for me is freedom for the user. Deezer doesn't even need to decide which keys people should use. Just expose these actions in the Windows app and let us assign our own global hotkeys. The same idea could extend beautifully to Android and Bluetooth media controls. Cars, headphones, keyboards and remotes already send Previous, Next and Play/Pause commands. I personally almost never need Previous Track. I would happily remap that physical button to Favorite/Unfavorite or Don't Recommend. Other users could choose differently. This would be especially valuable while driving. A steering-wheel button is a much safer and more natural way to tell Deezer “I like this” or “don't play this for me again” than interacting with a touchscreen.

There is one more idea that would complement this very well: optional floating feedback notifications.When I press my global Like/Unlike/Don't Recommend key, Deezer could briefly show an overlay above other Windows applications confirming exactly what happened, for example:
“Added to Favorites – Artist – Track” or
“Don't recommend – Artist – Track”

Then disappear automatically after a few seconds. The same floating overlay system could optionally show the currently playing song, including the cover artwork, for a few seconds whenever the track changes. I know Deezer has had useful integrations such as Waze, but it isn't realistic to integrate separately with every navigation app people might prefer. I used Waze for years, for example, but now use Sygic. A simple Deezer-owned floating overlay would work independently of whatever navigation software, game or application happens to be on screen. So the core idea is:

1. User-configurable global hotkeys on Windows
for Favorite/Unfavorite and Don't Recommend.
2. Configurable Bluetooth/media-button actions on Android
so users could repurpose buttons such as Previous Track for those actions.
3. Optional floating visual feedback
confirming the action, and potentially showing track information when songs change. The first two are the important part. The overlay would just make the whole system feel complete.

I genuinely think giving users this little bit of freedom would make Deezer much nicer to control outside the Deezer window, especially in cars and while working on a computer. I've wanted this for roughly ten years, so I thought it was finally worth putting the idea directly in front of someone at Deezer.

THX in Advance!
