In response to a request by a user, I spent a bit of time adding a new feature to TabbedInspector. Now you can make a TabbedInspector which takes an Object and a collection of properties and breaks those properties of the object into multiple tabs. This is particularly useful for model inspectors: if you have a model with a whole lot of properties, you can now organize them under various tabs.
For related reasons, I also increased the default maximum number of properties in an object to 100 (from 25).
If you're interested in playing around with this, grab the latest on SVN, go to HeatBugsWithUI.java, and uncomment the method:
public Inspector getInspector()
Recompile and check out the Model tab.
