Hihi, you can do some pretty funny things

(All GUI action, in All GUI action...)
For the name range, I prefer '-' because the 'to' is a text, it doesn't stand out from the two action names (where is the end of the first name? the beginning of the second?).
I tried partitioning with just the first letter. It works, but I find the result a bit empty, I prefer the full name. I admit it's a little confusing the first time, but you soon get the hang of it, so not a problem.
