JogglerPlus is THE timer utility program containing many features for the advanced user.
The number of timers that you can have active at a given time is limited only by the
availability of system resources. It provides five independent actions that can be
taken upon a timer's interval expiration-
1) issue a message and display a picture file
2) play a sound file
3) launch a program
4) close a program
5) start a different timer.
You have complete control of each individual timer and groups of timers through settings.

Using the remote control plugin, timers can be controlled from the MSDOS command line,
a batch file or shortcut. The plugin is licensed separately.
