Outdated themes any new coming?

Hi guys I was looking to change my site theme to something a bit brighter and more modern look but there really isn’t a lot of options here and to be totally honest the themes are now looking a bit dated?   Any chance of introducing some new ones anytime soon?    By way of a quick example I would like to do something along these lines with a form appearing in the main window like that but I was not able to do this on your current theme nor have any options re adding the likes of that via apps etc   https://smarterbusiness.co.uk/    As good as Boldgrid and its adds ons is, aside from the darker themes which are the best looking, the lighter ones do really look very outdated.
