1)
Having only one tab with a drawing file the tab still has the red “X” to close it, it lights up when hovering above, but nothing happens on left_click.
a) Close the tab (why not?)
or
b) Disable the “X” in case it’s the last tab.
2)
A similar issue is the right click menu at the (last) file:
The “Modify” and “Delete” are active but lead to an error message
[ bad, thing about “dumb user, wanta banana?”]
3)
Why is there the possibility to _create a project_ “on a file” ???
Brand new interactions and interfaces. 
Easy to use and quick to get started.
