4.5 RC Up and Running. Assessment Questions Suggestions

I've spent a GREAT deal of time administrating a 4.5 RC site that someone else installed without issue.

I'm very pleased! I'll make a couple of comments that I hope will assist others. I've still got a few issues..that could be bugs, or me missing something. Please let me know where I might need to correct something or if it's a bug in need of getting fixed. Ok, here we go:
1) ADMIN>USERS>CONFIGURE>PROFILES;
Will we soon be able to create/designate PIVOTS for USER defined terms? Example: "FAVORITE BOOK LIST" each book title should PIVOT to other members with same TITLE listed in their profiles. I don't think that this feature is built yet. I notice that if I choose a CHECKBOX or LIST SELECTION it PIVOTS perfectly. Would be nice to have it PIVOT as a SELECTION/checkbox for any field the ADMIN would like to be "PIVOTABLE" and then definable with what the USER inputs.
ISSUE: Updating profiles sometimes NOT saving. Reverts to already saved data.
ISSUE: HTML Text editor DEFAULTS to ON in profile this completely erases ALL data that was input in OFF mode I.e. LISTS are now completely GONE that were hand input! That's a very nasty one.
ISSUE: Shouldn't DATE in Profile follow the same formate as chosen in ADMIN: example 10/01/1967 I want to read 01/10/1967.

2) Image Galleries: Link shows up correctly on the top of the site... and says 'image galleries' when link is selected but it is not showing any images, even though there are about a dozen images uploaded. Image block on left side is also empty. What am I doing wrong?

3) Is Private Message working? I've set it up to write to author... but don't see it available to write a private note to a member within the site...? What am I doing wrong?

I'm sure I'll find or have more later. That's it for now.

Overall 4.5 is a MUST upgrade. No doubt about it. Thanks EVERYONE! ;-)
