To not only display this number, if you hover with your mouse, you could do the following modifications:
At first: If you don't see the total number of records on hover over the page numbers, you have to activate “LISTVIEW_COMPUTE_PAGE_COUNT” in config.performance.php
Search:
{if $LISTVIEW_ENTIRES_COUNT}{$PAGING_MODEL->getRecordStartRange()} {vtranslate('LBL_to', $MODULE)} {$PAGING_MODEL->getRecordEndRange()}{/if}
Add after:
| Total: {$LISTVIEW_COUNT}
Search:
var pageNumberText = pageStartRange+" "+app.vtranslate('to')+" "+pageEndRange;
Replace with
var pageNumberText = pageStartRange+" "+app.vtranslate('to')+" "+pageEndRange + " | Komplett: " + jQuery('#totalCount').val();
If you don't need the Information, which user own a filter, you could easily remove this information.
Search and remove
{if $GROUP_LABEL neq 'Mine'} [ {$CUSTOM_VIEW->getOwnerName()} ] {/if}
