I often have many different documents open in tabs but not in separate windows. I drag the tabs together so that InDesign's screen looks sort of like a browser with multiple tabs at the top. But only the selected tab is visible in the main windows. But rearranging these tabs in my preferred order is VERY finicky. I have to drag precisely left or precisely right, and about half the time my tab, instead of rearranging, opens in a new window. Frustrating.

The solution would be to recode so that when you drag a tab left or right to rearrange, OR to drag the tab for a separate window into a tab group, you have a buffer of a certain number of pixels above and below the tab group before you decide the user wants to move the tab, instead of into the tab group, into a new window.

Related to this, there is an option Window > Arrange > New Window for [nameoffile]. Why not an option for Window > Arrange > New TAB for [maneoffile]?

Thanks for listening.
