Dark Elixar Drill capacity - during boost

I noticed when I boosted the dark elixir recently that it became full after 6 hours (level 3). Obviously it would be nice if it had capacity for at least 8 hours when boosted (sleep time). Maybe it can increase when boosted and stay higher for a few hours after the boost runs out.

Yes it would be nice, but they already increased the storage capacity of drills once, so I don't think we'll be seeing it happen again. You'll have to wait until you get level 5 or 6 drills, which is when boosting becomes really effective anyway.
