limit for scnenes count in MAKE VTOUR / vtourskin.xml

Hello,
i'd like to limit thumbnails in my tour.
It means if I have 20 scenes in a tour but like to show only 15 thumbnails in thumbs panel.

For me the vtourskin.xml code is too complicated and I just think, that it shoud be done somewhere inside the vtourskin.xml in actions:
<action name="skin_startup">
<action name="skin_addthumbs">
<action name="skin_updatethumbscroll"> and <action name="skin_update_scene_infos"> . Some changes manually in variables like scene.count , sceneindex, lastsceneindex... ???

This question is probably for Klaus as a creator of the code.I hope.

I'd like to explain in this tour - I want to show only room thumbs and NOT thumbs of detailed photos ( last flat panos of newspapers and posters in the tour):

Well,
I made some progress.

I found more than 3 action wich are needed to be changed and add some tag in the main XML.
With the help of Tuur. Thanks Tuur.

I show later my result.
