In Maps Module, please enable simultaneous display of multiple GPS Tracks

Question

Hi LR4 team,
First of all, a big thank you for adding geotagging and mapping support in this version.  I was one of the (many) users who was disappointed that geotagging (as well as soft-proofing) did not make it into LR3.  This time around I'll gladly part with $99 to upgrade to LR4 as it has some great new features.
In the maps module, there does not seem to be a way to display multiple tracks simultaneously.  There's an option to switch between tracks (Map->Tracklog->Next Track|Previous Track) but it doesn't appear to be possible to display multiple tracks simultaneously.  This is a pain, especially if you load a tracklog which contains multiple tracks.  Many dataloggers will start a new track each time the GPS is power cycled (e.g. with battery changes).
Instead of cycling through tracks one at a time (as is the case in LR4 Beta), please consider implementing a multi-select list where the user can check which tracks he/she wishes to display.  Naturally the multiselect should also allow for "Select All" and "Deselect All" and selection of (multiple) ranges using the Shift and individual tracks by holding the Control key -- you know, the typical behavior for lists.
Also please ensure that LR4 hand comfortably handle large track files. I use a datalogger that records its location every 1-10 seconds throughout the day.  This results in a fairly large data set to process.  When travelling, I may not have the opportunity to upload from CF to LR and sync with GPS tracks for several days, which means that I may have accumulated somewhere in the range of 5MB to 50MB of NMEA track data (depending on the sampling rate) in around 5-20 separate tracks.  I'd like LR4 to be able to efficiently handle loading these tracks and tagging all newly imported images.  As above, it would be helpful to enable simultaneous display of many tracks.
Thanks!
PS: Love the animated (bouncing) trackpoint to disambiguate multiple images taken in close proximity to one another.

Just as a side question:
Have you ever loaded a tracklog containing different tracks belonging to more than 1 month?
This is what a tracklog with tracks from 10/14/2011 to 11/07/2011 looks like here:

Not a big problem, but also not nice.
