Data Set Assignment Editor

Data set assignment editor is nice way to assign multiple dataset to orgunit. As the Data set assignment editor has no save or clear button, any wrong selection is hard to control. For example the checkbox before the orgunit name which allows user to either select all the data set or un-select all the dataset it hard to control. It better to have a reset or save option or even a option above the checkbox which say select all. So that user know they are going to set all the dataset or unselect all the dataset.
