The "collapse/expand track" feature does not appear to be well-documented, even though this can be one of the most confusing features for new IGB users, who often accidentally click the "collapse/expand" button, which collapses the track and makes it look very weird. Because they have no idea how they got into that state, they don't know how to return to the previous state. And if they quit and restart IGB, something many people do with learning a new interface in order to return to a "base state" (recover from an error), it won't work because IGB saves the current configuration of a track and restores the configuration upon restart. The only way to recover from getting stuck in this way is to use the "reset the preferences to default" feature, which new users are unlikely to know about.

It would be useful to have a single page in the user's guide that explains "collapse/expand" functionality. If we had such a page, we could refer users to it when asked. Also, depending on how well we write this page, it might end up being findable in search engines.

For this task, write a user's guide page describing the collapse / expand feature for tracks. Make sure you search the user's guide with keyword "collapse" and "expand" to find images others have created that are related to this feature. Re-use them to save time, unless they are not well-down.

Make the new page of child of this page:

• https://wiki.transvar.org/display/igbman/Annotation+tracks

Additionally, we currently have a very bad explanation of the collapse/expand features on this page:

• https://wiki.transvar.org/display/igbman/Customize+track+appearance

Delete this section on "collapse/expand" from the above page.
