I sort of wish the D&D beyond app could have a spell point system like point buy. It works where you have a certain amount of points at each level, and a spell costs the same points as its level, where 5th lvl and up can only be cast once per rest (whatever the current system uses for spell slot resets). (I also took this idea from Blane simple, not sure if he made it or someone else) I just wish there was the option to change it to this at the dms discretion like how milestone and exp are chosen.

I couldn't agree more. I have always been disappointed with the constriction of the spell slots system, and I love the spell points variant. However, finding a physical character sheet for that system is already hard enough, let alone knowing that the app that I have been using for a few years now, which should have most (if not all) of the SRD variant rules represented by now, does not have the option that I as well as other play groups have been looking for. I hope this post makes it to the top of the list. 

Thank you. It's good to know that this is a good system.

I also find it nice that your a 3 year member and this is your first post.
