This revision is not considered as finished yet as I haven't added all the styling (namely how text in the comboBox is styled if it's selected)
The problem is that the space in the ComboBox is limited and as the capture mode names are quite long and the shortcuts can be quite long (is there any limit how long custom shortcuts can be?), there might be not enough space between the name and shortcut.
Therefore I would like to ask for possible solutions for this (Only display shortcuts with a specified maximum length?).
