I'm not at home testing this, just looking at the screeshot, but I notice, your many apps have a ui with lots of text and buttons and sliders always. I understand how this can be done with objects and events, but its a tedious process. Are you using a particular plugin or technique that's cutting out some of the tedium, or are you just more patient than me?
i know what you mean when you say 'tedious' !
In this project the U.I is basically 'box objects' and a couple of 'sprite buttons', with text objects on top of them. As long as the 'snap to grid' option enabled (on a very low setting ) it is suprisingly easy to create.
Dont get me wrong though, i have about 40 different 'back-up' versions each using different and various combos of sprite buttons, edit boxes, list object...Etc, and its took me about a week to to get to this stage.
