No feedback while loading data or changing layouts #365
Description
Note also that it seems particularly hard to use right now (on my desktop, in the latest chrome). There is no feedback on how to load the sample data sets (click? double click?) and when you do click (at least for me) it freezes for 10-20 seconds with no indication of what it is doing. At least that makes some sense because it is reading data across the network. But when I switch layouts it also freezes for 10-20 seconds before actually changing the layout (and makes other chrome windows act flaky at that point too). I don't remember this happening in the past.
