Using Nexus Ultimate, does it support horizontal subdocks ? can't find a way to activate this feature.

Assuming you are running v11.2:

Open the Dock Properties dialog for the dock you want -> Position & Behavior tab -> Sub-Docks button.

I'm willing to bet he's talking about shelf sub-docks, which is something I had pointed out a few weeks ago...

I hate to disppoint you mate but I was talking about Docks not shelf !
@winstep thanks, this option ain't available in previous versions eh ?

Nope, sorry.

Look, Winstep applications are rapidly evolving, with new cool stuff and tons of functionality being added all the time. For instance, for the next release I just added the ability to combine all those new dock mouse over effects - Heal, Spin, Squish, etc, which no other Windows dock has, by the way - with the Magnify effect, so you can actually have both at the same time.

If you register, you get headache-free access to all that as soon as it comes out, and sometimes even before, as one of the perks of being a registered Winstep user is that you get to try new releases before everyone else does.

mate to tell the truth I'm From PK, how can I register and pay ?

You can pay through Paypal, Credit card, Instant Bank Transfer, some debit cards or even Mail/fax as per the BMTmicro site.

Or you can do it the old fashion, pre-Internet, way, although it is always a risk: put a 20 Euro bill in an envelope, wrapped in THIS order form for Nexus Ultimate which you must print and fill out, and then send it to the Portuguese address printed in the order form.

Winstep has had orders from Pakistan before.
