I have had it. I tried different themes (color was the primary reason) and each gave me different functionlaities. For example, TechBlue doe snot have 'My Messages", 'Calendar", "Search" i.e. the same toolbar. Which themes can I select that will have the same default toolbar of SMF but color of techblue and Adorfa Multicolor (i.e. 2 themes) for 2 forums.
You can add those functions to the themes you want as long as you have sufficient space in the toolbar.
Post up your index.template/php files as attachments and I'll add the button codes for you.
Just make sure to let me know exactly which buttons you want added to which file. ;)
By the way: the calendar button will only show if you've enabled the calendar in admin, but you probably knew that.
If color was the issue for the default theme, have you looked at:
