XXX TO DO:

|
|
|
|
- reparse when source changed (maybe just a button would be OK?)
|
|
|
|
(or recheck on window popup)
|

|
|
- add popup menu with more options (e.g. doc strings, base classes, imports)
|
|
|
|
- add base classes to class browser tree

- finish removing limitation to x.py files (ModuleBrowserTreeItem)
