Great, but..

Kiwi is great, multi-accounts, calendar, google drive and other google apps also work very well, but when using wide gamut monitor with Adobe RGB profile, the colors are strongly exaggerated, Safari (El Capitan) works in this case better, because it displays the content in the sRGB (internet standard) even if you use AdobeRGB profile. So, work at it, and it will be really the best program to gmail!
