I can confirm that @newuserkantu knows lot about UI Vision
Another good source for UI Vision RPA custom development and training is to ask on Freelancer or Upwork: Can I hire a pro Kantu User to Help Me with Something?! - #6 by pleabargain
if it can work on 2 tabs at the same time?
There is no tool that can work on two tabs at the same time, but as @newuserkantu already said, you can use selectWindow to switch between two tabs.
Or you run two or more instances of UI.Vision at the same time by using browser profiles.
