You can remove the panels you don't need in 'public/assets/javascript/og/layout.js'.
Tabs are defined from line 31 to 137 in this format (in this case the messages panel):
new og.ContentPanel({
title: lang('messages'),
id: 'messages-panel',
iconCls: 'ico-messages',
refreshOnWorkspaceChange: true,
defaultContent: {
type: "panel",
data: "messages"
}
}),
To remove the panels you don't want you can just delete them or comment them by surrounding the code betwee a /* and a */ like this:
/*new og.ContentPanel({
title: lang('messages'),
id: 'messages-panel',
iconCls: 'ico-messages',
refreshOnWorkspaceChange: true,
defaultContent: {
type: "panel",
data: "messages"
}
}),*/
Make sure that the last panel doesn't end with a comma.
We will add configuration options to hide panels on a future version.
To remove the tags panel delete or comment lines 215 to 225.
