Add nav-search-filters file
re-factor members panel to use bp_nav_menu, remove existing 'ul' tags in 'nav'  tags (bp_nav_menu renders full markup & needs modifying?)

Add get_template_part for new search-filters.
Run through account screen files  - remove bp_options_navs
Add temporary style enqueue of vert menu styles for working concept - will need refining and moving to main styles when ready.
Forgot to add/version nav menu stylesheet
First pass for messages screens re-factoring, re-configures messages.php with new switches, adds markup and scripting for messages-loop.php and single.php and test data for compose screen.
Add message thread excerpts to messages-loop.php - N.B. with current implementation the left column message thread loop always shows full messages even when we are viewing a single message in full or full message and it's related follow ups.
Move dynamic class for read/unread threads to li element
Wrap unread count span in 'bp_message_thread_has_unread' conditional to hide if it is read.
Correct from /to meta - function renders anchors so adjust anchors to spans to hold from/to text and user name anchor link.
Add avatar call for thread loop - sans markup - attempt to work simply with the img element.
