I'm very surprised, and extremely frustrated, with how clumsy and difficult Acrobat DC is. It's not good.
The "Edit PDF" button should not take us to a separate area. We should just be able to click on an editing tool and get to work. The editing is dismal. It is next to impossible to resize or relocate text after it is typed. The only way I've figured out to do this, is to click back to the Document area (why did I have to leave it in the first place?), click on the Select tool, then go back into the Edit PDF area. And then I need to select the text box immediately, or I'll not be able to select it at all.
About 50% of the time, I will click on the Add Text (T) tool and begin typing, but not see any text. I need to cycle back between the document and the Edit PDF area several times again to sometimes see it, or I just need to close my file and close Acrobat and begin again.
It is ridiculously hard to select an object I created. For example, I draw an arrow. I want to resize it and move it, but I can't. I have to cycle yet again between the Document area and the Edit PDF area and hope for the best.
Also, why can't I have two rows of tools in the Document area?
