Andre, given the amount of spam we have been getting lately a first post with a link to another product from a user with a Gmail account is highly suspicious.
Normally I wouldn't mind at all, but given that it might actually be spam (and you only posted it as an example, which I already saw) I will only remove the link.
Assuming you are for real... the height of Shelves can be adjusted in terms of rows in one of several ways:
1. By clicking and dragging the respective *tab header* up *while the Shelf is open/expanded*.
2. By double clicking the tab header while the Shelf is open. This will expand the shelf so all the content in that tab is visible (obviously up to the limit of the screen size). Double clicking the tab again will collapse the shelf so it shows the default number of icon rows - double clicking can also be used to this effect if you expanded the Shelf by manually dragging the tab header up as described in the previous section.
3. By setting a new default 'number of visible rows when open' setting for that Shelf: Shelf Properties -> Appearance tab -> More Options button -> changing the default 1 in 'How many rows of icons would you like the shelf to display when open' to whatever you want.
So... you were saying about not being able to adjust the height?
