Aero Windwalker (ID: 0000001799453d1d) Voted 1 ★ - Updated 06/27/2019 A very powerful tool. But it should include "storage.sync" method so when using multiple computers, the scripts can be shared. Also, window in JScript tricks is not the same window in the webpage, making it less useful in many cases.
