This may seem to be a very strange analogy, however it is a very good fit for EasyEst Estimating Software.
What it means practically speaking is that users of EasyEst almost never have to close or back out of a screen, window or data field to go some where else to make a change or view information.
Many other estimating software products force the user to close or back out of where they are in order to add or change anything else. Many times you forget where you were when you want to return.
You will really appreciate EasyEst Estimating Software when you are checking your markups and your mind suddenly remembers out of know where you entered a wrong value in another place in your estimate. Just leave where you are at and go to the item and make the correction all the while the work you are doing on the markups is still in view.
