One way to share your Watch Window group setup (blocks in a group, name of group, configuration like update interval etc.) with another is to export it, and then import it into another copy of Hyperview. This can be accomplished by choosing Export Group Setup... from the Group menu.
This will allow you to save the configuration of the currently displayed group as a .grp file.
Note: Export Group Setup only exports the group setup, NOT the data collected in the group. In order for someone else to have access to the actual data, they would need to copy the actual csv data files to their own watch window data file location. Note that Hyperview currently supports only one data file per block, so if you already have a data file for a particular block, and you copy in another for the same block, you must choose which one you want Hyperview to load into the watch window (Hyperview will load whichever one is present, and named appropriately).
