trance is a translation (or localization) tool.
Unlike a standard text editor, trance provides three text fields: one for the original language text, one for the translated text, and one for notes on the translation (for future reference and collaboration.)
trance also has a navigation pane that allows per-chapter, per-page, and per-dialogue organization.
trance v01 (source code)
Note: trance is only compatible with hiro/GTK at this time. Although this port can be built on Windows, GTK itself has some stability issues with the Windows IME. Plus, installation of the GTK run-time DLLs is rather involved. As such, binaries are not provided at this time.
trance is released under the ISC license.
