Please remove the text (GPU Preview) in the name tabs.
They take up needed space if you have several files open. I know I can turn it off if I turn off GPU but would rather not.

As I encounter numerous glitches and bugs when using a second screen—most of which are “resolved” by switching between GPU and CPU preview mode—the addition of the mode in the tab is very handy.
For example, unplugging the external screen from my MacBook often results in an empty InDesign document. Changing the preview mode makes the pages visible again. I’ve encountered this bug on many different machines, OS versions, and InDesign versions.
Of course, Adobe should fix these bugs in the first place, but for now, I’m just glad I can easily see which mode I’m in.

I can see no good reason for this text being there in the first place. What is the point of it? To show that we are using a graphics card? Why? Come on Adobe, remove this pointless feature!
