I get that dA wants to "refresh" it's looks from time to time...
changing the way the page behaves, overall color schemes, location/look of page controls, etc. 
Yes the changes made can be removed or turned off...
and yes they do give some more display options...
HOWEVER...  the limitations of widget placement & the way it was done brings up other issues for me.

I don't mind showing the some of the awesome works that I took the time to , 
But now MOST of my page real-estate is devoted to showing the works of others.
If you're gonna force that on me, then shouldn't I get to choose which galleries I want to display????
 
Bottom line: MY PAGE WAS REARRANGED AND FEATURES WERE ADDED WITHOUT MY APPROVAL!!!!

NOT COOL!!!

 

It's like having your landlord enter your apartment while you were at work to do some plumbing or electrical repairs...
and rearranging your apartment & adding a bunch of furniture you didn't want... 

HEY dA, STOP Fenging with my shui!!

I guess the biggest question must be: 
Is this behaviour something dA figured that I'm likely to continue pay for????

Right now, I'm thinking NO.
In fact, ATM, I'm so ticked, I don't even want to bother coming back.
