KOReader is one of my favourite pieces of software, makes the ereader experience so good. Especially for pdfs where you can swap to landscape, reduce margins etc. Has a cool feature to highlight and create a QR code you can scan if you want to share snippets. Used it on my old kindle and currently on my kobo ereader.
