(1) You can now change the size of the hotbar icons. Making them "too big" will cause them to wrap into two rows. Either make them smaller, or resize the hotbar. This 'change the size' feature is now standard in SoE: r-click on the hotbar to get the full set of options.
(2) You can resize any hotbar and make it vertical. Think of the vertical bar as a horizontal bar of size one, that raps into 10 rows
It is just a matter of resizing the hotbar to fit your needs.

The only thing I have seen like that is Goldi's Start Window, which (among other things) has a Harvest Window (accessed via a H button in the Start Window). You can find that mod here:
