One simple flaw.

Developer, please allow the ability to "Hold shift to translate." No one wants to sit there on a webpage and be constantly blaseted with pop up translations.
We need to be able to translate only the words we want to know.

Developer Response ,

In the upcoming 2.6 there'll be "Hold Alt to translate" option, please enable that from the main app when it's released.

Handy App, one single flaw.

Works as advertised for me. However... you might notice that "Permissions for Safarikai are: Can read sensitive information from webpages, including passwords, phone numbers, and credit cards on all webpages.... in addition to seeing all webpages visted"

I do not understand what this means technically between the verbage used and behavior in actuality. However, it would seem out of scope for the purpose its intended for.... to have the ability to record all of this. Just make it a paid app already and don't sell my information. What a shame.

Developer Response ,

Hi, some related discussions:

I believe that's the default permission configuration when developing a Safari extension. Please check other extensions. Many would show the same warning.

No I won't make it a paid app. It's open source, and personally I use it myself from time to time. Believe it or not I don't want your information or money. The extension doesn't send anything to anywhere.

Privacy concern

Why does Safarikai need to "see all my browsing history?"
