Condense or concatenate command for Todo plugin...

[monodemono]

It'd be nice to have a way to somehow concatenate or compress todos in the Todo plugin.

What I mean is, let's say I add 3 things to my todo list:
todo add walk the dog
todo add take a shower
todo add do the dishes

then I list them:
Todos for monodemono: #1: walk the dog, #2: take a shower, #3: do the dishes

then I take a shower, but I don't do the other two, so I remove that from the list:
todo remove 2

then I list them again:
Todos for monodemono: #1: walk the dog, #3: do the dishes

then I remember I didn't finish my homework:
todo add do homework

list once more:
Todos for monodemono: #1: walk the dog, #3: do the dishes, #4: do homework

Well this is ugly and makes it harder to keep track of how many things I have to do. It would be nice if there was a way to fix this:
todo sort

and then when I would list again:
Todos for monodemono: #1: walk the dog, #2: do the dishes, #3: do homework

This wouldn't interfere with todo's priority because all it would do is close the gaps, not fill them in, so everything would stay in their correct order.
