I have a somewhat unusual use for my Boox Max Carta, and I am looking for app suggestions. I play weekly with a ukulele club in an outdoor environment and the e-ink display, screen size, and light weight are ideal for use as my music book. What I need is the means to quickly close a (single page) pdf song sheet and open a new one selected from a long list, and hopefully to do so quicly and without using the hardware buttons on the Boox. I am primarily concerned with the life span of those buttons, but secondly, actuating the buttons with the device sitting on my deep shelf music stand at some distance from me is a bit awkward.

Now here's the rub. The built in STORAGE function launches a pdf in a way which leaves a back arrow on the top line which I can tap on to exit the pdf reader. This is good. What is not good about the STORAGE function is that the icons are so outrageously large that the number of selections on a single page is very small and I cannot seem to page scroll with the stylus. So I have tried several different android file managers which give me quite reasonable means to select and launch my pdfs. But now the pdfs do not have a soft button way to exit.

I have tried to find a compatible “soft back key” app but to no avail. Any suggestions? Also, I am looking for the fastest stable pdf reader. Don't need any features, just display the pdf. The fastest I have found so far is the Google PDF Reader, but it sometimes goes off to lala land.
