While I can't recommend SiteBuilder, there are at least 3 or 4 things that will make editing easier for someone who has created drag and drop pages.

1) SiteBuilder's "Arrange" menu has options for a grid. Select "show grid", and you see some "ruler" types of lines. They they don't show up in preview or in published files, and they offer a calibrated way to tell where you are in the page.

2) If you select an image, and right click, it brings up a screen to set the image's horizontal and vertical coordinates. These are absolute values relative to the top left corner.

3) The same editing screen shows the image size, but if you try to edit the position and the size at the same time, SiteBuilder seems to get confused. Deselect and reselect the image between operations. To resize the image to Original, use the 5th item down on the selected image right click context menu.

4) When you insert a navigation bar, it is in the same position on each page. If you have content you want to transfer to a template page, you can select all the items and the navbar on the donor page, and paste them into the target template page. The nav bar makes the content distribute in the same relationship as it was on the donor page(relative to the anchored nav bar). If you end up with code for 2 nav bars, delete the extra.)

4) Under the "Tools" menu, at the very bottom, there is a preferences option, which allows you to import from "other sites". That gets around the problem of trying to set up a test site, and then transfer the files to production.
