All plug-ins can run at the same time. However, only one plug-in can have access to a receiver. In other words, it is not possible to have several plug-ins accessing the same receiver at the same time.
Concerning the charts: I have offered the author of the ACRF2 plug-in to use the older version of the RFXCOM charts (for free). To check the availability and functionalities of the charts in the ACRF2 you have to ask this in the HS forum.
