Tartarus v2 layer overlays and keypress combos

I just got my Tartarus v2 and I’m pretty happy with it, but I have a few things I want to do with it, but I cant seem to figure out how.  1)screen overlay: I’d like a screen overlay to pop up when I change keymaps to the keymap name. That way I am 100% sure which keymap I just scrolled to or accidently scrolled to. I understand that there are lights on the device that show the keymaps, but that is stupid. I don’t want to look down to figure out waht keymap I’m on. Without a screen overlay, I feel I must dedicate keys to specific keymaps, and then that starts eating up keys on my Tartarus, which brings me to my second problem. 2)combo-key macros: how do I assign a macro/function to pressing 2 keys at the same time? I get the feeling that this can’t be done, which sucks, bc this would make the device much better. Then I could just keep my fingers on the home row, and use my pinky finger to change from attack macros to build macros or something like that. It could essentially quadruple the ability of the macropad. If anyone knows how to do this stuff, please let me know. Otherwise, I hope the razer dev team can add these features in a firmware update or future model. thanks.
