Please consider adding two small features that will make working with it a lot easier:
1. Option to save and load our current selection of used things in custom fitness list and also their weights. This is important to have backup especially in advanced selection, also sqx sometimes hard to say why makes some problems saving this wrong - for example few times over months I realised sqx changed itself some single selection from "Minimize" to "Maximize".
2. Simple switch above list to: Show all options of list / Show only my selected criteria. This will make fine tuning weights much, much easier as having many parts selected and scrolling list up and down to check/change weights is always a pain.
Thank you!
