Is it just me, or has the new Redwood UI removed the ability to select multiple lines on a saved search when in Edit mode? I'm used to doing small mass updates that way and even deleting test records in bulk that way. Am I missing something?

Just had occasion to use it in a Sandbox that's been upgraded and it worked like it always has for me. Maybe try clearing your cache?

actually you cant see that these lines are selected but if you press shift-delete, then those lines gets deleted. That's a bit scary behavior

Weird. I got the exact same behavior I got from pre-Redwood in that when I selected them, there was the little dotted line box around the lines that would be deleted. Wonder if it's some browser issue? I'm on Chrome.
