I recommend saving the keyword filter settings so that they "stick" across multiple multiple reports for different keywords.

For example, I run a keyword report on one keyword in Keyword Explorer and set a filter based on position and keyword difficulty. Then if I enter a different keyword to run another report, all of the filtering settings reset to their default state, and the position and keyword difficulty filter disappear and need to be re-entered.

Instead, it would save time if these settings would stick across multiple reports, then you could add a button to "clear filters" or "reset filter to default".
