Yeah this will be really helpful. The other gacha i play Konosuba Fantastic days has a similar ui where if you click on any mat it shows the total quantity you have.
So in sgm if you skip dailies and receive 20 fire shards, clicking on it will show you the total quantity along with the name it currently shows. This can be inplemented in take a break/ daily relics /gifts too with character skill points and relics being shown in that very screen. I will try to do some photoshopping and will post it here later.
