I suspect there is a potential for an enhancement, so judge me please:

I have my project open with no other files loaded into editing than the Untitled (it is optional, otherwise on last document closed it will exit).

When I click on a file in the project, the Untitled gets replaced with the document I chose.

I expected the Untitled stay.

Otherwise I have it only for the purpose of not making the editor exit.

Why we cannot have just an empty background kept instead, not the file?
