The Toolkit is the only reason I'm not going back to YNAB4. Seriously, the Toolkit is THE BEST.

This is such a great tool! I love all the different options; lots of good UI improvements and also some useful columns and other settings. Favorites include compact account names (now I can see more on my small laptop screen), right-click on transactions for menu (why isn't this standard in YNAB??), changing the behavior of the enter key when I enter transactions, and showing the upcoming transaction total (really helps me to plan ahead with budgeting).

I'm having the same problem with not being able to log in when you start using more features.
I know this extension from chrome and it has a lot of potential once they fix their bugs in firefox.

Hope another update comes soon, Can't stand the dates starting on a sunday!

Everything was working great until I started adding more features (and perhaps even until the latest update). Once I toggled more features on, YNAB has stopped allowing me to login easily. It continues to give me the "Uh-Oh! Something has gone wrong likely having to do with internets and tubes. Refresh your browser to get back in business." screen at login, until I toggle Toolkit off.

I tried to file a bug report, but the bug button does nothing. And then I tried to revert my Toolkit settings back to default, and the red button doesn't do anything either. Would be a fantastic app, and add a ton of useful features to YNAB, but it's still a little buggy. Waiting for another update to make it a little more stable.
