It's been over 4 or 5 years now when you decided to mess up the trello with automatic formatting of urls.
It's still messed up. Try yourself:
- Change your profile settings that do not show fancy link cards, just the most plain option "inline"
- Create card, edit description, add text, paste url from clipboard
- click the hovering remove link button. This is because you don't want the url to be a link but plain text
- Click save
Whoa, the url text got now automatically converted into "smart inlineb button".
No I don't want that, I want it to show as plain text in the card preview. How hard is it for you to understand ??
