Is it Multisite compatible and How?

Hello,
Does your plugin (v.1.3.0) work on multisites? Should it be network activated?
If so, I wonder whether it will solve our problem.

We have recently created a (wordpress v3.8) subfolder/multisite installation (newdomain.com)
On an older (subfolder/multisite) installation the uploaded images for site oldersite.com/mysite01 have a URL like:
http://oldersite.com/mysite01/files/2011/08/ph-300×225.jpg

BUT. On the new -exactly similar- installation, they show up as:
http://newdomain.com/mysite01/wp-content/uploads/sites/7/2013/12/ph-300×225.jpg

We need the newdomain.com photos, for site newdomain.com/mysite01 to look like:
http://newdomain.com/mysite01/files/2013/12/ph-300×225.jpg
(the old way)

Would we be able to achieve this by using your plugin AND creating the folder
http://newdomain.com/wp-uploads/files/

Can photos uploaded for site http://newdomain.com/mysite02/
show up as: http://newdomain.com/mysite02/files/2014/01/ph-300×225.jpg

If not, do you have any ideas on how to do it?

Thank you in advance,
for your time and work

PS: Bonus Questions 🙂
Does it work with mapped domains?
How does it behave with CDN?
Cache plugins?
What happens with already uploaded images?
