When the beta (or production version for that matter) crashes on re-opening I get a list of auto-saved queries - thank goodness [:)]
However to recover tabs, I have to click on each one separately, then click recover. When there are a lot of queries open this can take some time as evidenced by this screen capture:
Feature request: One of either:
Recover all button
or Select All/None buttons.
or Default to all documents being selected so that we can de-select the ones we don't want to restore...
