Hi Arvydas,
thanks for using take4strelka, the premier tool u can get ;).
The generated Code is placed in ${user.home}/take4strelka/generated, but u can configure that... Options->Plug-In Preferences->take4strelka. On that tab are all Preferences for the take-plugin. I hope the labels are self-explaining, but if u need further help, i could send u my thesis on this project with detailed information about the usage and internals of take4strelka. Anyways, feel free to ask on this group and i will be glad to answer as good as i can.
Cheers, Bastian
