Getting this on Macro panel

Hi Mark, the Synced Tabs stop working (correctly) months ago. In general the text tool freeze it Glyphs app.

By the way, I'm getting this on the Macro panel:

```
Traceback (most recent call last):
     File "plugin.py", line 123, in SyncEditViews
          otherView = otherTab.graphicView()
AttributeError: 'NoneType' object has no attribute 'graphicView'
```
