Having Sketchbook and Gallery open at the same time

Hi,
I just got a Galaxy Note 10.1 2014 version.
I mostly got it to use as a mobile digital sketching tablet. I was really hoping for a multi-window option and was ecstatic to find out that this is one of the features..... but then was disappointed to find out after I bought it that Sketchbook Pro doesn't support multi-window! I was really hoping to be able to have Sketchbook and Gallery open at the same time so I could sketch from a photo reference.

I did find out about an app that will let you use multi-window for any app, but it requires root. I've never rooted anything before and I'm pretty novice to tablets/smartphones so I'm a bit cautious to root it so soon.

I also heard that Gallery has the option to resize, move and pin on top or to the side of another app. Is this true? Can I have Sketchbook open, and have a resized Gallery open at the same time and pinned on top so I could still sketch and see the photo? If this is the case then I won't have to root the device.

Thanks!

 

Damn, Pen Window would have been a perfect alternative, but the apps for pen window are even more limited, and honestly i don't know why they chose those apps, they seem to be the most useless of any apps I could think of for that utility. Most of them require internet, and I want to be able to use apps when I'm not in wifi range.

I found a list of non pre-installed multi-window compatible apps that don't require rooting, but is there a list of non pre-installed pen window apps or is it just those 7? If there was a photo viewer that is all I would want.

 

Awesome, thank you so much!
