Hide Activity Details (+ Tweaks) for Trello is a free Chrome add-on developed by Mark Kenny. As the name suggests, this add-on allows users to hide activity details on Trello cards. When viewing a card, all the activity history is usually displayed at the bottom, which can be overwhelming and cluttered. With this add-on, users can easily hide this information by clicking the "Hide Details" link.

Additionally, Hide Activity Details (+ Tweaks) for Trello offers the option to hide completed checklist items. By clicking the "Hide completed items" link above the checklist, users can focus only on the tasks that are yet to be completed.

Furthermore, this add-on brings back the functionality of displaying card label text in list view. Users can choose to show or hide the label name along with the color strip.

Lastly, if users have two-factor authentication enabled, this add-on conveniently places the cursor in the authentication field when it appears.

Please note that this extension is only compatible with the most recent version of Chrome. For reporting any issues, users are encouraged to provide specific details about the problem they are experiencing.
