Implement custom pointer acceleration profile
Feature summary
A few months ago Wayland added support for custom pointer acceleration curves. Reflecting this feature would allow users with needs not covered by the default profiles ("flat" and "adaptive") to access this feature.
How would you like it to work
Being an advanced use case, I think it would be OK to have to manually set the acceleration parameters through dconf, and expose a "Custom" profile in case the user has defined one.
Relevant links, screenshots, screencasts etc.
- Wayland documentation about pointer acceleration profiles.
- libinput patch introducing the feature.
Note: I don't feel very legitimate opening this issue as I'm simply an end-user, but I've been hoping something like this would come for the last ten years. I'm not sure I can provide more technical information.
