I'm a happy user of the DPT-S1, I consider it one of my best investments, thanks a lot of job well done.
I'm enjoying reading and annotating my material on the device, still the zooming function bugs me quit few times, some of the materials I read on the device have big margins and small font, I find myself zooming the page and use the side bar to turn pages (which also add an annoying black bar at the bottom), when I want to read, I want the least distraction possible, so as a work around recently, I started creating a cropped version of these documents on my computer, which is fine, but it's an extra work and waist of time, beside, I can't do this for all documents if I need to share my notes with others (and preserve the original format of the document)
Could you please consider adding a crop function in the future? it doesn't have to be a new thing, it's just the current zooming function that you have without the need to the side bar and a bottom bar, the ability to turn pages by sliding, and the ability to save the crop setting so that next time I open the document it shows up as I left it.
Many thanks, and I hope my suggestion find it's way into the next update.
