I would like to have DPA use more screen width when it is available. I have a 1920 x 1080 display, but have to do a lot of horizontal scrolling (for example, in the Blockers tab).
I agree with this. I had opened a similar vote and was pointed towards this one.
Also agree, STRONGLY.
When we change the chart config to see, say top-40 SQL, rather then the default, we have to keep scrolling right once we've named a query. That should be completely unnecessary - the pane should be as wide as the entire chart plus all named queries in all columns. You'll probably need to offer a "Wrap Named SQL at 32 characters" (or whatever number), otherwise long-winded query names will look a bit daft (IMO) especially if there are more than 15 to show...
