@kevinh I've only just installed 1.9.0 and have just tested a search or two and find the "new search goes back to beginning of group" a little weird too. Your #1, #2, #3 seem quite reasonable. Alas I also don't use saved searches much, so can't comment in #4 (yes, keep meaning to use them more ...).
One workflow I use a
lot is "^F, type something, <enter>" and I am used to that starting from the current position in the current file and searching forwards to end of current file then on to next in the group and so on. With the proposed Find First and Find Next, which type of search would <enter> choose? And if it was Find First, could this pretty please be configurable?

I suppose logic like "last used Find type" might be a bit more difficult?
PS: Thanks as always to you and Diap for another release!
