One of the computers I am testing VEB on is a Surface Pro 3, and the config screens are not finger friendly (fine with a pen tho). Granted neither is half of 8.1, but I digress.
Perhaps after getting feedback on what devices have it installed, if a decent number of tablets are running Veeam, either some mods to the UI could be made, or a small touch-friendly shell app could be released for tablet users? Just two ideas of ways you could do this. But demand needs to be there first I would think.
