Hi, Scott. No argument with you (or with Tod). 
This thread started with the topic, When opening a database, take me to…
–Inbox
–Root directory level
–The following folder
I often find it useful to have not just one but all three of those views plus some open documents, as I have done for some time with my main database.
I spend most of my time in my main database. Right now I’ve got 8 windows open in that database, and those 8 windows have been in use through repeated closings and openings of that database, each window retaining the size and position that I had assigned it.
There are three Three Panes views for that database: Root, Inbox and a group. The left sidebar is shown in the first two, but not in the third. All three Three Panes view windows occupy the full screen of my 13.4-inch screen.
There are 5 document windows open. Two of them are full-screen and the other three have different sizes and positions.
Perhaps just because I find it a convenient size on my computer’s screen, all the Three Panes or List view windows in all of my databases take up the entire screen. Whenever I open a database in which I’ve previously been working, that’s the size shown for such view windows.
If I open a new document window, it will open taking up the full screen area (except for PDFs, which I usually read in Full Screen view, anyway). But I usually reduce the size of open document windows and often place them side-by-side, and they remember their size and position if left there during a database close/reopen event.
If I close a document window that I had sized and placed, it will resume that position and size when next reopened. I like that. When I’m reading a document in its own window, I can place alongside of it a document in which I take notes. Now that pair of documents will ‘remember’ the sizes and positions and I can resume my reading and notetaking tomorrow or next month. Although I will have lost the scroll position in the source document by closing and reopening it, I can remind myself about that position in the notes document, so that I can go back to where I left off last.
So that’s the basis of my remark that I know what to expect, and I get what I expect.
Perhaps if I used different sizes for different Three Panes database views I would encounter the behavior you mentioned. I haven’t tried that. Maybe my finding that windows and views are stable in size and position is just a result of the way I set them up and use them. I’m certainly not claiming any superiority of my workflows over other possibilities.
