Multiple Windows in standalone
Would be great to be able to open multiple Zotero windows in Standalone. Use cases: each window could have a different Collection open, allowing for comparison across contents or simultaneous views into the different Collections. For Mac OS, a different Zotero window could be open in each Space to serve different projects divided across the Spaces.
One thing I'd change is Gracile's suggestion: tabs should be of the breakaway sort, so they can be pulled off as a separate window, combined with other selected tabs, and allow easy comparison between collections.
I was hoping this would show up in Version 5, but no such luck.
