Interesting post! btw: As you know, I am an EIAS user too! so, since we do lots of TV ads and VFX. our goal is bring EIAS asap "into the 21st. Century" as you wrote hehe..
I hope we will please, lots of request from our user base! Including you of course :)
Yes, we are a small team with a lot of passion to EIAS, trying to be clear about what took so long on this upgrade, some important changes we did, generated a "cascade" effect, pushing us to re-write from scratch more and more the old code.
And recent external changes from Apple added more delay on our side, Apple killed 32 bits apps, Apple killed Quicktime on Windows and a lot more.. so, we had a balance between big code changes, new features to make us and the user base happy, lots of optimizations to show we are faster and easier than the other apps for sure :)
Our goal after v10: make smaller upgrades to be always in contact with our user base, hearing all demands and make always EIAS fresh!
Thanks a lot
