I am very disappointed by the recent changes to Trello. It seems that Atlassian is trying to make it look like Jira or Confluence (i.e. slow, unusable, bad).
Atlassian just decided to kill markdown editing by default (for some obscure corporate reason I guess). Seems like there is a solution to it: https://community.atlassian.com/t5/Trello-discussions/Would-love-to-have-markdown-editing/td-p/2603253
But today I noticed that the modal that moves cards has new clunky dropdowns that are very buggy in Firefox.
These changes do not add any value to users. They just destroy existing workflows. These are very bad product decisions.
Please put your pens downs and stop messing with Trello, or try to understand the spirit of the product first.
