Thanks for your thoughtful comments and analysis of 2GIVE.
One of the other things we're particularly proud to have is our "automatic garbage collection" that when a send is performed the wallet will actually try and grab 20% more coins than necessary to complete the send instead of doing a "best fit" that all the other wallets use.
This has the effect of "defragmenting" the chain over time as smaller unspent outputs are bundled up in the "change" transaction.

I too am one of those core wallet users that like to burn whole unspent outputs however after encountering 1% of the remaining balance as a Charity Fee using coin control I opted to let the wallet decide and was intrigued to see how the wallet gathers unspent outputs from the smallest amounts while rolling-up change towards the main address and of course glad to see the flat 1% against just the spent amount. So for mainstream users I agree coin-control is a non-starter but having a view of coins in the wallet I find useful.
