well in 2d I use Last Object, wait for target, target last usually.
I tried the KR functions, and I can't say I like the "mine all" functionality. It keeps trying to mine anything in range, which means if you are on a corner box you might start mining the wrong section. It also likes to try mining further away than I expect.
You can always stop a macro in KR these days with "esc".
It's not perfect but it's ok. I try experimenting with it now and then.
The good stuff is you can set spells, skills and things on the hotbar and then just hit the number for them. So set up an emergency recall macro and then set it to "1", for example. I am going to play with the custom UI stuff eventually, but haven't had the energy yet.
Oh, and the little dirt patches are VERY hard to see in KR.
