Today I was helping a company finish up a TYPO3 installation. They were using somewhat long descriptive page titles and then using shorter titles for the navigation. Since the page titles are used as labels in the TYPO3 back end page tree, the long titles were making it difficult to to figure out which page was which.
They said they would like to use the navigation title for the page tree. I told them, "I do not think it can be done as I have not seen it any other way."
You would think that with as long as I have worked with TYPO3 I would know better than to say something like that.
After a few minutes I thought, "It makes sense to have that option, and with TYPO3 being the king of options, could it be possible?" I first looked at my copy of TSconfig (2/07 edition) but found nothing. I then did a search on my definitive documentation (Google) and came up with a couple of bug tracker references. I read them, and sure enough, the feature was incorporated into the core sometime around version 4.2.
Put the following in the User TSConfig:
options.pageTree.showNavTitle = 1
After you log out and log back in, your page tree will display the navigation title if it exists otherwise the page title will be shown. This makes sense to me since users are used to seeing and using the navigation title on the front end.
Thought I would pass on that discovery. Also, if anyone knows if there is a later version of TSconfig, let me know. I did not see a copy on typo3.org.
