Hi all, I've added a task queue-type mechanism to Reason. This fixed for me some of the issues with multiple projections showing up, as well as this weird lingering sometimes-it-doesn't-work thing. Anyway, Reason is working great for me, so testing from everybody out there would be super handy. Just make sure you're on the latest version everywhere, and it should be good to go. https://bitbucket.org/yt_analysis/yt/changeset/b8a4c0e7cd40/ When Britton was here a while back, the two of us and Cameron chatted and came up with three things we wanted implemented before it could go out: 1. Sometimes slices/projections silently failed. This is fixed for me, but your mileage may vary. 2. We need an "Open File" dialog. 3. A button to paste the contents of a single cell. I am thinking this would be a hideable toolbar that shows up on hover in the upper right of a cell, and then you can download, paste, or copy to the current cell the contents of the cell in question. Anything else? -Matt PS This is the last thing for a 2.2 release. After 2.2 goes out, we'll start using the Bitbucket bug tracker for everything.
