this plugin is 100compatible with parallax mapping, it also supports Galv's Layer plugin and MZPrimeParallax, both of which are plugins that allow more than 1 parallax layer.
However when using the tool to edit parallaxes, the colliders are STILL defined in grid format, this is for several reasons, and will not be changed any time soon... but it is planned to allow drawing directly onto the parallax.. but it's a lot of work to re-write the tool to handle this.. so it won't be for a while..
Currently there are no push/pull mechanics tied directly into this tool, I may be adding a seperate plugin in the future to extend the plugin to handle such features but currently it is not implemented in any capacity. ^^;
