My favorites so far are. Moon Reader+ and Smart launcher 2.
I was using Nova at first, but find Smart Launcher is perfect for my needs. You have a small circle of apps on the home screen and swipe over to see the widgets. I keep only 5 app on my home screen, but it's easy to add more. . I think my favorite part of it is the app drawer. I don't know too many with the horizontal configuration. Also the play store is available in each tab of the app drawer. I've installed it on my tablet now too. I like it enough that I bought it, but it's available for free, although I don't think the free one allows widgets. Also if you want to turn the back light on in t68, just double click on the button under. Boox. You don't need to go back to the stock launcher. Just an FYI for anyone having issues with that.
I also attacked an image of the big keyboard I use since I kept hiring the wrong buttons on the t68. I think it's called big button keyboard and it's free and adjustable.
The previously mentioned WiFi switch widget is also really useful, my fav is WiFi widget by Robert burger since it updates with info as you connect and tells you the network. I have 2 at home so I need to know which is being used for calibre companion.
