This has been an issue for me since E:WOM.

My mouse doesn't have a scroll wheel, hence I can't zoom in and out using the Builder's Forge or Cartographer thing.

I do have a scroll function: Click button 4 and I can scroll up/down/etc. using the mouse.  Click button 4 again, function disabled.

I use the Logitech Marble Mouse/Trackball btw.  I have RSI/CTS issues, and this mouse solves that issue handsomely.  It's been on the market for several decades now, btw...

Anyways, not being able to zoom makes designing structures using the Builders Forge and such problematic for me, as I only have the 'default' zoom level to work with.

NORMALLY, I would accept this, but where the + and - key  zoom in and out ingame, it only makes sense that these same keys perform this function in any utilities for Elemental.

So, I'm politely asking that such functionality (keyboard assigned zoom) be added to the Builder's Forge and such.  This would of course be much easier than trying to get you guys to code implementations for every mouse iteration on the market.  Not all mice have scroll wheels, for example... 

Pretty please?
