There used to be a plugin for it...
But it stop getting updated when they changed the way gems are upgraded in game. You use to have to do everything one at a time. Now you can upgrade 256 marquise to imperial at a time. Rinse and repeat as needed.
Once I get a stack of 5000 of a marquise gem, I go to jeweler, set it to upgrade to 256 imperial. I click the create button 6 times. It leaves me with 392 marquise gems leftover and makes 1536 imperial gems. Then I let the marquise start to build up again. Then I repeat.
After I do this 3 times I have over 4600 imperials.
Once my marquise stack gets up to 5000 again, I just turn off that gem type in the Trinity settings. Who needs more than 5000 marquise and 5000 imperials?
And over the course of a month+ to get that many, I only had to hit the create button 18 total times over 3 trips to the jeweler.
