LOL yeah I had a bad habbit of beginning to add features and not finish them off properly or document them....heres another one though..
Make a new folder in your Construct directory (C:\Program Files\Scirra\Construct) called 'Images' (the installer was ment to do this part but didn't heh...u only need to do this once)
Now in the animation bar, go to an animation and right click and select 'launch explorer'. A folder will open containing all the png files of that animation which construct has exported. You can then drag and drop these into another image editor like photoshop or something, edit them, and hit save. When you are done switch back to construct and there will be a message box saying 'Click ok to reimport the images that have been exported to explorer'. Click the ok button and the changes should appear.
However this feature was somewhat incomplete because it doesn't allow you to modify hotspots, or add additional frames...so that was a work in progress.....think it's a worthy feature or should I remove it ?
