Joplin is a free, open source note taking and to-do application, which can handle a large number of notes organised into notebooks. The notes are searchable, can be copied, tagged and modified either from the applications directly or from your own text editor.
Save webpages to read later, and eliminate cluttering of bookmarks with sites that are merely of a one-time interest. With Pocket, you can read at home, work, on the plane, or during your commute; even without an internet connection.
