When we have an analysis which includes lots of tables it would be great if number of rows for each table would be displayed next to table name. This could be in client in data table properties next to the table name. If last average loading time would be near row number that would be perfect. This would help analysts to optimize and quickly define issues with long loading times. Now user has to open visualisation for each table one by one. To get loading times user has to reload each table one by one also. This info could be available and stored in the current session immediately after opening the file.
