I'm surprised this wasn't thought of originally but it's tedious to have to input values every single time you assign a group power. I should be able to save a list of values for use later, like as a default but with a list of them. This would be helpful because I have only one (lang) power, but it makes me not want to switch the power to another group because that means I have to re-list every value again but I also don't want to buy another (lang) power. There are ~269 values for (lang) power. No one wants to sit through and do a bunch of those for each time they re-assign it. The feature should work similarly to this:
The save button should be next to the 'OK' button. When you click it, you are prompted to title it for easy identification when you use it again.
The current 'Default' button should be replaced with a dropdown menu. When you click it, you are prompted to choose one of the saved values in addition to the default values that were created by xat. You should then receive another prompt saying: 'Are you sure you would like to load [...]?'
This should also apply to powers with a list of values, such as (gcontrol), (link), (bad), (gsound), and any other powers that I missed that work similarly to the ones listed.
