From turingart, branch of CUBiC:
P!Mark is a screen prompting solution, which presents instructional text using a global system window, which permanently stays in front of all other running applications. Thus P!Mark is well suited to add instructional information to screen movies, product or support presentations.
P!Mark is based on the concept of frames, which get displayed step by step. Each frame is composed of a bold-face title, a text and an icon. A set of standard icons is included.
Once a user finished editing frames - which are stored in an embedded database - he starts the show and P!Mark presents each frame step be step. Frame transitions smoothly fade in and out.
Using a global system hotkey [SHIFT + OPTION + RETURN], P!Mark advances to the next frame of the show.
We published this release as a BETA, although we don't know of any issue/bug. We'd like to get feedback from you!
