It's easy to add buttons. Let's say you want to add the Media button, you would do it this way:
1. Download the full version of TinyMCE 2.1.2 from SourceForge:
http://sourceforge.net/project/showfiles.php?group_id=103281&package_id=1114302. Unzip the archive to your HD and browse to the plugins directory
3. Copy the media directory to the plugins directory of your CMSMS TinyMCE module
4. Edit tinyconfig.php, change line 83 from:
$plugins="cmsmslink,fullscreen,advimage,simplebrowser,paste,advlink";
to:
$plugins="cmsmslink,fullscreen,advimage,simplebrowser,paste,advlink,media";
5. Open TinyMCE in Admin and click on the Toolbars tab. Change Toolbar 2 from:
bold,italic,underline,strikethrough,separator,bullist,numlist,separator,outdent,indent,separator,undo,redo,separator,cmsmslink,link,unlink,anchor,image,charmap,cleanup,separator,forecolor,backcolor,separator,code,fullscreen,help
to:
bold,italic,underline,strikethrough,separator,bullist,numlist,separator,outdent,indent,separator,undo,redo,separator,cmsmslink,link,unlink,anchor,image,media,charmap,cleanup,separator,forecolor,backcolor,separator,code,fullscreen,help
That will add the Media button for you. Use the same process for any other 20 or so buttons you want to add.
