I'm not sure if this is the right place for this suggestion, but if it isn't, please move to the appropriate forum, thanks.
I would like to suggest that it should be possible to at least group cores by their integer value instead of their decimal value so that you know you have 6 cores at 99, 9 cores at 90, and so forth, instead of having them string out and fill in your inventory, giving poor beleaguered players like myself scrolling calluses. Seriously, that would be a helpful adjustment.
Also, a toggle to prefer your lowest powered cores instead of your highest, to conserve the 100's (which do group together nicely) and to burn through excessive inventory of partially used cores faster, which, if you're not going to fix the grouping, would at least help to minimize it.
Thanks for considering my thoughts on this subject.

John Romero
