I would really like Galeon to enable pulldown menus within smart
bookmarks on the task bar. In the following I will describe how this
could work from a gui point of view.
 
First I would go to the bookmarks menu and create a subfolder named
"journals" within the personal toolbar. When creating it I should set
some flag telling Galeon that I wish the folder to be a "smart
bookmark folder".  Within the folder "journals", I would create 2
smart bookmarks
 
http://www.arxiv.org 
http://www.arxiv.org/abs/%s
 
Physical review Letters 

http://link.aps.org/ejnls/volpage?journal_code=PRL&volume=sdfgnbd&issue=&journal_code=L&pageno=%s
 
This should result in the creation of a single bookmark on my personal
toolbar. This single bookmark should consists of a pulldown menu and
some white space (For writing the information for the %s'es)
 
 1) First there should be a pulldown menu that enabled med to chose
 between "www.arxiv.org" and "Physical review Letters"
 
 2) Depending on my choice of journal there should be one or two empty
 spaces in which I could write the information corresponding to the
 %s'es (one white space for http://www.arxiv.org and two white spaces for
 Physical review Letters)
 
This request has also been posted to the galeon-dev list, but I was told
that it was better to submit a bug report :)
