I have a template that I use throughout my app. At one point in the user interaction the internal process takes about 30 seconds and then paints the screen with a new tab. I'd like to have the words "LOADING..." appear across the first screen, until the next screen appears. I was thinking I could do this with the Template Parser Class. I have never used it before. Is the modification of the template just temporary?
Or perhaps there is a better way such as showing a busy flag?
