I'm not sure where to start with this and was hoping for some advice. I'd like to be able to quickly display (and then dismiss) a slider that can be adjusted through scrolling which adjusts something like display brightness. The volume adjustment slider in the menu bar on a mac has the behavior I'm looking to simulate.
I'd rather stick it into a workflow rather than code a separate app since Alfred is always open. The only thing close to this I've noticed is that the Packal Updater workflow somehow loads a window running php.
If anyone has an idea on where I could start I'd appreciate it.
