I opened the gallery, how I don't remember, using LO Draw to create some floor plans. Went well. Recommend it. However, when I went back to accounting in the spreadsheet, I could not get rid of "the gallery". The logical place to find how to add/remove it is in "View". Not there. I found it in tools, after a lot of searching, including the Help System (to no avail). As there is no ellipse ( ...), there are only two options: 1. Display it. 2. Do not display it. (Binary ). A more intuitive UI might be a check mark, and maybe even put it in the View menu.
That's it.
