My log file is in not in the .setting directory but in \Application Data\syntevo\SmartGit\2.
Ah, my bad...Perhaps it's in .settings for me because I'm using the portable version.
Anyway... considering all that, SmartGit is probably what I'll try to use more in the next week.
Looking forward to any observations
BTW, I wanted to search the history of a project via the log window and was stumped initially. I learned that "search as you type" (they call this speed-search apparently) seems to work. Was this obvious to you? I didn't find this in the docs...it was again via a posting to that support list.
Then I spent a while trying to figure out how to search for subsequent occurrences -- finally after trying a variety of combinations, I hit on using the down (for next) and up (for previous) arrow keys...feels odd but at least something works.
On a related note, I've started to investigate gitk and am noticing that it seems to produce more search results than SmartGit for the same search terms in some cases. It appears that SmartGit doesn't load all commits  by default and the searching only seems to take place over what's loaded -- once sufficiently more commits are loaded, additional search results seem to come up...
 Found a "Load all commits" menu item via the Query menu.
