#7 Removing workflow invocations is inconvinient

[Jacek]

When one removes a completed invocation from the list the cursor always jumps to the beginning of the list. It is a bit unexpected especially when the list is long and does not fit the window (scroll bar appears) but the invocation being deleted is at the end of the list.

I'd expect the cursor to either:

• stay at the same position (jump on the invocation following the one deleted) if there is following invocation on the list,
• move one position up if the deleted invocation is the last one.
