I'll still fix bugs in PowerCards, but adding features and making major changes is likely not something I'll undertake. The internal structure of PowerCards imposes some big limitations on what can be achieved. The reliance on handouts, the inability to use Rolls as variables or in conjunction with other rolls, and the like preclude a lot of functionality. Since PowerCards and ScriptCards can run in the same game, you can continue to use existing PowerCards while creating things that require more complexity in ScriptCards. If you are reliant on PCMHelper and its macros, there is now a 5E Action Menu ScriptCard script that essentially duplicates this functionality and doesn't involve the mind-bending mess of replacement variables and templates that PCMHelper does.
