2sxc 8.6 brings large improvements on the in-page toolbar and the APIs to customize it as you need it. Create custom toolbars, change alignments, create custom buttons or create action-links without the toolbar. Here's how:

Customizing The Toolbar
You can now create any combination of
- Custom button groups with "..." (more) rotating between groups
- Buttons calling standard actions (like edit) with customized icon, label etc.
Read more about it in the 2sxc wiki.
Customizing the Look and Feel
Toolbars can now be customized in terms of
- hovering right/left/none
- place the (more) "..." buttons to the left/right
- always show (even if not hovering)
