Can you add please to the table context menu "Table Count" or "Rows count" feature.
While properties does provide "num_rows", that value as good as statistics are, which usually on development database(s) is not the case.
It can be just as message|alert screen. it does have to be asynchronous with the window it invoked from and should have cancel button - large tables count might take long time.

For features like this you can use the Browser Extender Plug-In. It can be downloaded from the Plug-Ins page.
