I downloaded BTT earlier today and do not feel like I have a good grasp on the program yet, so forgive me if this is completely wrong.
When making a TouchBar Button, it seems that once I alter anything within the button's "Advanced Configuration" that the button no longer appears and I get the "You have not yet configured actions in BTT" button appearing on the touchbar instead.
I trialed this with a simple "new window" button specific to my browser and fired off a few new windows with it, but once I went into the advanced configuration and selected the box for "Icon only, ..." no button appeared when I re-selected my browser window.
Thanks in advance.
