However you are not a new user. In what situation you need to explicitly close a project?
I have understood that a long time ago there was no dialog but it was added because many people wanted it.
I do close projects from time to time (though indeed rate). Typically if I make to many "recent files/project" jumps and I'm unsure about the project I have opened.
Speaking of history. Originally IDE didn't have many features out-side of the project scope. That's why there was not an option to close one.
Right now IDE has many options that could be addressed without having a project opened:
* packages (installation/removal);
* configuration of IDE itself and/or packages;
* some other tools in the system;
If I need to change FPC version or directory or select a new package to be installed, why would I have to click "New Project" -> "Application"? (just from the usability point of view?).
I'm tend to right all sorts of IDE extensions, as you know
And IDE extension package cannot be a part of any project (as it doesn't really make sense), so I actually have to have something opened to continue editing the package.
IDE does allow to have a project opened without any source files opened.
So isn't it consistent to have IDE opened without any project opened?
