One Affinity photo feature that is dearly missing for me is a keyboard shortcut to increase and decrease opacity of the currently selected layer. I would need this, so I could map this shortcut to a MIDI controller and be able to quickly set a layer's opacity with said controller. Since there is an ever increasing number of people who use MIDI controllers as quick input devices for the graphic softwares, I believe I am far from the only one who would benefit from such a feature.
Currently there is only the possibilty to use the up/down arrow keys (+ shift optionally) to increase and decrease the opacity once I have set the focus to the opacity field. This does not really help me all that much as I would always need to focus this field first, before i can start to change the opacity. It would be great if there could be a global shortcut for this as well, preferrably also with the possibilty to use shift optionally to increase the increments to 10.
I would not care if it is an obscure shortcut or if it is even turned off by default, as soon as there is any shortcut for this MIDI users could make use of this and map it to their controllers.
