when using addbutton to add several buttons to a created toolbar; the toolbar seems to accept the additional 'addbutton' commands as the toolbar expands according to the number of buttons added however only the first button is visible while the others are hidden in the toolbar.
i'm not sure if this is a bug in addtoolbar or addbutton or somewhere else in km toolbars or if there's an additional command that should be used for adding more than one button.
tested on 1.5.3
more details in this thread:
p.s. if it is indeed confirmed as a bug, if possible; can it get fixed in a 1.5.4 release(along other confirmed bugs) before 1.9 migration. thanks.
