First, I was wondering why only some of the filters that have a list of things that can be unchecked with an erase all or reset button (pencil button) while some don't. For example, the match numbers filter and some of the history ones have the button. Makes sense they have it with 10 or more things possibly to erase. So, it seems it'd be handy to have this available with match winning numbers or match tickets in file for pick 3 {with straight, pairs, etc. there's potentially over 10 things to erase] And with the history filters, number differences sum and Unique number differences for e.g., don't have the option, even though there could be a lot to erase if you used 10 or more levels. Having more erase options would just save a little time when putting filters together.
Something else too, with the custom analyzer, if you paste a filter group in it, even if you name the filter group, it doesn't show up[it's still called filter group]. If you're looking at several groups in the same analyzer it can be a little hard to keep track of them. There are numbers beside the filter groups in the order they were put in which does help.
Neither of these topics are too big a deal, but thought it might be good to make note of them anyway.
