GBrowser - Custom Track visualization

[cascoamarillo]

Hi all,
Minor question regarding how to visualize features from a custom track (gff3) into the Genome Browser. So I work with the Generic Genome Browser (version 2.40) from an external server (collaboration work), and when I upload my custom track, gff3 file, like this:

##gff-version 3
scaffold_1	RepeatMasker	transposable_element	21377	21447	18.3	+	.	ID=TE1
scaffold_1	RepeatMasker	transposable_element	66377	66437	11.7	-	.	ID=TE2
scaffold_1	RepeatMasker	transposable_element	68947	68978	12.5	-	.	ID=TE3

it is showed in the browser like this:


But instead of showing transposable_element:RepeatMasker (2nd and 3rd columns from gff file) I want to see the ID when you place the mouse close to the feature. I've bee looking at the GBrowser documentation and the config files without succeed. Any help from the GMOD gurus, please??

Thanks
