Two suggestions.
1) Make it so you can sort the Ally Members page by defpoints. At the moment you have to click each member's name and look at their defpoints on that page 1-by-1.
2) Defense priorities. Have 3 or 4 categories of priority (high/medium/low/nodef or green/yellow/orange/red). Have two different ways of automatically assigning members to these priorities: by number of defpoints, and by percent rank in defpoints.
Number of defpoints is straightforward. Have 3 integers you could define for low/med/high. So low could be more than 5 points, medium more than 15 points, high more than 30 points, nodef is anyone that isn't low/med/high.
Percentage is fairly simple too. Again, define 3 integers. In this example we will use hypotheticals of 20, 40, 80. High priority = top 20% of members ranked by defpoints. Medium = top 40%. Low = top 80%. Nodef = the leftovers.
Also, make "nodef" an option. So if you tick a checkbox, you have a nodef category. Untick it and you only have high/med/low.
If you dislike idea #2, but like idea #1 (because who couldn't like idea #1?) then please express your like/dislike for each idea individually.
Sorry if any of this post seems incoherent. I spent last night DCing til 3am and slept 2 hours.
