The project manager adds a tab to the sidebar with a page containing a tree-list for project files, a list of workspaces, and a list of sessions.

Geany has built in commenting functions, and Djynn adds some additional commenting functionality. It is recommended to change key bindings [Menu: Edit->Preferences->Keybindings] (scroll down to the "Djynn" keybinging group), should these functions be preferred to the built in ones.

Sorting of selected lines in files ([aA-zZ], [a-z-A-Z], [Zz-Aa], [Z-A-z-a]) or reverse order of lines.

Encoding & decoding of selected text, at the moment only two formats (Base64 and ASCII), though more may be added later on.
