Idle Online Universe RPG

Now that we have bank and most guilds have buildings that cost millions to upgrade, can we have new buttons to invest/move more than 100k stones at once?

+1, and the leaders of a guild would definitely like this when they want to move stone form the bank to a building.

a "donate all" would be nice. 

That is usually what you want to do, especially when donating to the bank. It also reduces donation spamming the guild chat

(another 5 characters)

Something similar to selling stones/wood would be nice as well. (with donate all option)
