MP means market place.  Although my final renders are usually Iray, the other viewpoints allow you to move your stuff around much faster, try using the wireframe, wireshaded, wire texture shaded and texture shaded. I often switch between the viewpoints because these allow me to move things faster. If you are using a tablet with your computer, you can use the View Tab to move stuff around quickly. I also use the Tool Settings tab for this.  You can also use the Parameter tab and key in the location, I always have to estimate how far to move the items. If you are using the keyboard shortcuts, that can be a great help.In Daz Select Edit View and you should see some shortcuts to navigate around the screen.

One of the things I do when rendering is to have my renders go to a window instead of a file. Once the render looks the way I want, I save that render to a file.

The setting for this is found in your Render tab and locate the Render Target section then change it to new window. You can pull the window off to the side while it is rendering. You can still see your workspace, but you can not do anything in it until the render completes or unless you stop/cancel the render.

Here is a screen shot of a product I am currently working with - It is the Keita Far East Club and the character is her G9 male.

As you can see there are many props here. In this situation I simply click on the item I want to move, click on the parameters tab to see the settings and estimate how far to the left or right I want to move the item, then I type in the location in the X trans section or z if I am moving it forward or Y if I am moving it up. I am using the LitWire frame viewpoint. Tablet user, you can select the item using your pen and drag it to where ever you want.

You always render through a camera (this is for those that are new to Daz Studio)
