Here are some improvements I would very much like to see happen (some of which we had but were taken away in the latest updates):

Text boxes:

Normally you could adjust the size of the text next to the 'T' symbol which would then stay the same for the entire document, now I have to adjust the sizes with every text box I make (it always goes back to size 24) = see screenshot

We used to be able to stay in the text function, now every time i close a text box it goes to the lasso function, every time I want to open a new text box I have to click on 'T' on my keyboard or my screen. = see screenshot

The text sometimes dissapears when closing the text box (sometimes it reappears when opening the text box again, but not always). This has made me lose some importants notes from class.

This significantly slows down my note taking in class. Not every powerpoint is the same size, for some classes 24 is insanely big to write in.

Shapes:

I never had this problem until the latest update, but whenever I make a shape (circle, square) I can't add any other shapes, lines (made by holding) into the shape. If I make them outside the shape it's very hard to select the shape (by tapping) without selecting the whole 'square'

The previous probably has to do with the fact that the shape now has the same properties as a sticky note (clicking inside the shape selects the shape and everything in it), I don't see how this is a useful since everytime i want to make a table I'm constantly selecting the whole thing instead of just putting my hand on my screen to write. Selecting the entire shape and everything in it can be easily done with the lasso tool.

The shapes function now exists two times? One on the big tool bar and the other on the Pen toolbar. Seems excessive, no? = see screenshot

Mutiple tabs:

While I love some of the latest updates, we all would like to see the ability to open multiple documents in multiple tabs like on the iOS version!

Lagging:

The 'app' lags so much it's insane, this is so annoying when taking notes (text function) in class (having to keep up with what the professor is saying) and when making my written notes (which is kind of what the 'app' was build for in the first place, no?)

Make it an app:

Make it a real app, this will probably already help with the lagging issue all of us are having and so much more.
