With the new pagination functionality of results in the Workspace, clicking 'Select All' only selects all records on that page (up to 100).
I think it would make more sense if 'Select All' selected every result in the workspace (even with pagination of 100 records) and there was a second option called 'Select all on page' for the current record set of 100 rows.
The same would work with 'Clear All' as at the moment we have to clear the selections page by page.
I raised a similar suggestion for this - we need the best of both worlds. we need more buttons for 'select all results' 'select page results' or something of that vein
This is a feature that used to be possible in the previous IE version, now having to click on each page and "select all" on each page individually takes so much more time
