I love having TOC and HOME buttons in redundant places. Having them buried deep in the menu may be redundant, but it's also consistent, and I do occasionally use those. Having them in the bottom and top bars is wonderful -- it means I don't have to find them in the menu when I need them, and it's one or more clicks fewer to get where I'm going. I use both the home, toc, and (transient) collection buttons in the top and bottom bars extremely frequently.

I don't use reading settings much, but it doesn't take much space, and maybe other people use it.

The refresh button is needed if you just added a book from the kobo store and want to download it immediately. Also, on the pocket screen, the refresh button will cause newly bookmarked articles to download. Use of those will vary depending if you use those things. (Note: the main refresh button gets both new books, firmware updates, and pocket articles. There's a separate refresh on the pocket screen that just gets pocket articles.)

Davidfor calls it a sync button, and that is what it does, but I notice the pocket articles specific one says refresh.
