<p>First, thank you for the comprehensive report with all the information we normally have to ask for.</p>
<p>You noted that this has been the behaviour of Geany projects for some time.  That is because it is the intended behaviour.  You see, a Geany "project" is nothing much more than a named session file, it keeps a list of a few settings and the files open.  Therefore if a file in the list does not open it <em>should</em> be removed from the list.</p>
<p>So a Geany "project" is not like projects in Visual studio and some other IDEs where they need to know all files in the "project" to provide some extra functionality, like symbol management or build management.  To get something like those sorts of functionality you can try the project plugins (there are several).</p>
