Using Ctrl-A, you can mark all filtered rows in a visualization. However, when there’s additional Data Limiting, this marks more rows than what is actually visible which I find rather unintuitive. Of course you can use the mouse to drag a rectangle which covers all rows, but in tables where you have to scroll or also in a scatter plot this can be quite inconvenient.
I'd like to propose to change the behaviour of Ctrl-A to mark all visible instead of all filtered rows. If that's not an option please implement some way of marking all visible rows.
