Katalon Recorder vs. Selenium IDE: A faster, easier way to create automated tests in browsers

How can I put a time to wait between actions?

I just using Katalon and compare to other it is very simple!! Already tried Tricentis Tosca but the navigation is not very good for me.

how fragile recorded test?

How do you edit the script once it is recorded in Recorder? My recorder freezes, can this be done in Studio?
