TL;DR
Enable "use filters" on inserters when the player selects the square to select the filtered item.What ?
Currently, to enable a filter on an inserter, you have to click the checkbox for "Use filters", and then click the square to filter the item you want. Would it be possible to just click on the square to select the filter, and that would automatically tick the "Use filters" checkbox, saving one click? The player wants to enable using filters when they click on the square to select the filtered item.(By extension, could also apply to the override stack size silder/textbox, as well as clicking on "Spoiled first" or "Fresh first" to enable the "Spoiled priority" checkbox.)
