Nice! Does it support opening in incognito mode for dev work needing to avoid caches?

I haven't explicitly added support for that, but that's a great idea and will consider adding that.

Since it's just a matter of passing the right args to the browser, what one can do in the meantime is add a shell or Powershell script in the Apps tab. Though, currently adding custom apps isn't available in the trial.

Linklever does have support for browser profiles. It should find them automatically for the major browsers.
