It's about keeping things easy for me to update. I'm already overwhelmed with my life and Gems of War has cut my productivity on my novel in half. With the current system I just have to look at a number and then make sure the search criteria are there and done. If I have to spend time interpreting images, that's more work.
I already sacrifice writing time every week to make these updates. I know you're also an active member @Shimrra and do a lot for the community, but I've taken on too much and I'm just trying to muddle through.
