You can usually easily clone any remote, but I haven't been able to replicate the Basic remote in particular. The layout isn't determined from the local layout/remote files. There is an older version however included in the remotes folder, that allows added buttons (so you could add a small row down the bottom with F11).
To play with it & see if it suits your needs (there are buttons for left & right click instead of tapping the trackpad), you need to change a couple of things in this file:
C:\ProgramData\Unified Remote\Remotes\Bundled\Unified\Main\Basic Input MT\meta.prop -
meta.hidden: true - change true to false.
meta.id: Relmtech.Basic Input Multitouch - delete this line
Then restart your server and the remote should show up in the 'Input' category after a few seconds.
Also, unfortunately it doesnt look like it's possible to remove/modify the bottom toolbar:
Hopefully this a planned change, seems popular on forum.
