I thought I saw something about this, but couldn’t find it…
Is it “safe” to go back and forth to edit between Elementor & Microthemer in separate windows?
If so, are best practices simply saving after editing?
Yes it’s fine to use Elementor in a separate browser tab. And I recently added an option to make that workflow more convenient.
Go to Settings > Integrations > Sync Browser Tabs
With that option enabled, Microthemer will reload the site preview when you save changes in Elementor. And Microthemer’s styles will automatically refresh in the Elementor tab whenever you make a style change in MT (without reloading Elementor).
By the way, version 7.1.6.7 fixes a display issue when loading Elementor 3.10 inside Microthemer. Some one just reported it. I thought it worth mentioning in case that was part of the reason you wanted to use separate browser tabs.
