Probably something that only I miss: the file name of the open document somewhere in the app. For example, below the display for the number of vertices or in the top line of the window. It is not possible to open multiple files at the same time, but when I take a break, I am often unsure whether the file I am continuing to work on is the right one. Especially since many of them often look similar. I think having the file name visible at a glance would be a cool feature, but not a particularly important one…

Just as FYI- if you tap the File button, the file that’s currently open is displayed as a picture (last save) with the file name on it.
Thank you very much . But I knew that… Sometimes I have three or more almost similar versions of an Object in different files. So for me it would be comfortable, to see at one glance, without any clicks, in the working space, which object I am working on. But as I said, that’s just me and it is not so important.
