iTALC makes it possible to access and guide the activities of students from the computer of the teacher. For example, with the help of iTALC a teacher can view the contents of students' screens and see if any of them need help. If so, the teacher can access the student's desktop and provide support; the student can watch the teacher's actions and learn from them. Alternatively the teacher can switch into "demo-mode", where all the students' screens show the contents of the teacher's screen. Furthermore, actions like locking students' screens, killing games, powering clients on or off, and much more can all be performed via iTALC.

You can rename files using patterns, search and replace, substitutions, insert or delete text, or even rename files manually. You can also rename images using their EXIF tags and music using their internal tags.

There are many chat apps that support OTR encryption for verifying messages. Many use multiple chat apps, including one for desktop and another for mobile, or one for Mac OS X and another for GNU/Linux or Windows. The trust relationships are only stored locally in the app in a format that is specific to that app. Switching between all of them means that you have to manage your trust relationships for each app that you use.
