Looks great, BUT..... – Sketch 3D Review

So, playing around with the app, it looks like it has some great features and is capable of some amazing things- BUT, there are simple things that just.... aren’t intuitive. The main toolbar, for example. It has a couple big, clearly marked buttons to close it out of the way- But I cannot for the life of me figure out how to OPEN it again without quitting and restarting the app. I’ve clicked every visible icon, tried tapping and sliding from every edge and corner, nada. I can even open the help tags for all of the toolbar items- WITHOUT ACTUALLY OPENING THE TOOLBAR. Just a list of descriptions of the buttons which were there a minute ago, and no clue how to bring them back.
