     * removed a leftover debug output that printed every search string of the log widget to stdout
     * fixed the option to copy the gate library into the project directory in the netlist import dialog staying enabled when the gate library is detected automatically, in which case there is no file to copy and the option had no effect
     * fixed action enable behavior in View Manager when deleting an entry
+    * fixed Python editor tabs repeating part of a file name with several dots, e.g. `quirk.v2.v2.py` for `quirk.v2.py`
