Slack - I really don't like the glossy feel about it. Maybe I just don't like all the bot noise, all the notifications (yes, I can disable them but then I would rather not use it). It might come across as absurd but I kinda preferred Hangouts. Just text. Would have loved something minimal and lighteight, w/o trillion features, and of course with native apps.

Jira. I just hate it. I despise it. What makes matters worse is my manager is a Jira fanatic. I think he is obsessed with it. One needs to shift in his seat "create a bloody Jira ticket". I, and many others, suggested simple ways to do things or even many GTDs. Many others teams use Trello and other tools but he has to use Jira.

Google Docs. Yeah, I don't like it either. Mostly how it's overused and abused.

Okta based login system. Logs me out every 30 minutes even though I choose to be remembered.

Intelliji or Webstorm or Android Studio. They are just bulky. I tried using other setups but since everybody else uses them it's difficult. (not forced to use these though).
