Trojitá is an email program ("client") focused on IMAP email accounts, where the mail remains on the server but is manipulated by the software you run on the computer under your fingertips. It is designed to be simple (it can be built using only one single dependent library), and fast and efficient over the network, economizing resources and limiting data transfer. Its GUI is intended to be uncluttered and efficient, and it provides "expensive mode" data transfer, that reduces the length of its conversation with the server to a minimum. It is a stand-alone program, not part of a bigger or more complex suite. As it is under development, some features are still missing.
