I'm thinking in creating an action to deselect every item in a Tab, even items selected in pages that you are not seeing. I'll like to know your opinion about this.
I mean: If you filter a tab, for example column name start with 'C' and select 2 items and after that you change the filter, column name start with 'X' and select 3 items and after that you clean the filter and apply you'll see all items in the Tab but probably you don't see the items selected. If now you want to change the selection you need to deselect the items selected but, how do you know what items are selected? how do you deselect all items? You can't.
So I'm thinking in creating this action and add it to default actions in list mode.
