Glad to hear this!
I personally find it still a bit of a pain, but it's always getting
better :)

Interesting idea! I think drag-and-drop to reorder the lines would be
very useful. Another missing feature I'm remembering is the possibility
to sort the entries by clicking on the columns. Both of these should be
<famous last words>relatively easy to implement</famous last words>.

For renaming I'm a bit less sure. What would be your use case? In our
case, the data in the entries is taken directly from the trace, so it's
already the "true" values. If the user was to modify it, how would they
restore the initial value?
