yes, the documentation on this site for the theme override is extremely limited and definitely confusing…
the single page on this site talking about the add_theme_support function was very vague, and not worded well… certainly giving the impression that it WAS necessary in order to override.
to use custom pages/loops/etc, do i still need to have the /buddypress/activity/file.php in my theme?
lastly, i don’t like the idea of being required to load another css file to override styles… i’d prefer to just use the styles.css file. it also makes writing the css a pain since everything requires the use of the #buddypress ID… not very elegant IMO.
with 1.8 it was working great, i had the default styles off, and was able to add my bootstrap classes, and style only what i needed.
