I can't install 0.44pre in TB3.1.1 with Compatibility Reporter 0.5.1 -- says it's "Not compatible". Do the ".rdf" strings need to be updated ? Do you need a Mac tester ? Post a reply here:

I liked what I saw when tested previously, but I'm now using 3.1.1 instead of the 3.1a1pre I was using before...
