Guitar Capo Setting
The guitar capo feature is located in an unexpected place, i.e. it's a property of a text element. It would feel more natural/intuitive to find this in the guitar strings setup. (This is the case in both Guitar Pro and TablEdit).
I realise that staff text gives more flexibility, in that the capo setting can be changed at any point in a score, but this is not really useful in practise as the capo cannot easily be moved whilst you are playing.
Workaround: read the MS manual to remind yourself where to find the capo setting.
