The beta version has a different ID than the regular iMacros V1.1.1, so you can install both version parallel.
iMacros for Chrome V2 runs on Windows and Linux, but not yet on Mac OSX.
Known issues in this version:
* Please note that the current iMacros V2.0 can read and run iMacros from bookmarks. but it can not store macros in bookmarks. Please use V1.1.1 for creating iMacros inside bookmarks. Please let us know if and how you use the iMacros as bookmarklets feature, and if you want to us to add the "store macro in bookmark" feature to V2.0 again in addition to the new ability to store macros as text files.
