You might use multiple Gmail accounts and want to stay productive with all of them and create documents in Google Drive all from one place without having to change sign-ins.
I can get distracted having Google Chrome or Mozilla Firefox open because of all the bookmarks I have saved. Many years ago after using Microsoft Outlook, Sparrow, Spark, Apple Mail, and Mozilla Thunderbird, I just couldn’t find the best email program for me that worked well with Gmail.
Eventually, I beta tested Kiwi for Gmail and later was grandfathered in to the full-featured release. It’s my best tool. It’s not an offline program like Microsoft Outlook, Apple Mail, or Mozilla Thunderbird but Gmail can go offline if you set it up whether you’re in this program or in a web browser. It acts more like a desktop wrapper of Gmail with added features. There’s a new Lite version if you only need to add two accounts.
