First off, gSender is GREAT. Just moved from UGS and it is so much better.
MINOR suggestion.
I am often editing other designs during a cut. I had the UGS window underneath, but with the bottom right peaking out so I could see how much time left.
Your status position is probably great for your controller display, right in the middle, but if using a laptop as controller having the status in the lower right would be nice.
I don’t know if you are aware of the remote option. Running a “clone” on a tablet or phone, might be an alternative to consider having on the side when designing. It gives the info you like to see and full controll of the machine. If it’s not what you seek in the long run, it can at least be a temp solution untill your suggestion gets implemented. (if)
