Hide Activity Details (+ Tweaks) for Trello

By: Mark
Hides all the activity entries on Trello cards. Optionally hides completed checklist items too.

Features & Capabilities

Hide Activity Details

When viewing a card, everything that was ever done to that card is displayed at the bottom. This is far more much information than most people care about, and it cluttered it so that comments were swamped. You can hide this by clicking “Hide Details”, but Trello doesn’t always remember your choice. You can set this extension to click that link for you every time you open a card. Activity details are always there, if you need them. Just click “Show Details”.

Hide Completed Items

I use checklists all the time, and only want to see the items I have left to do. You can hide completed items by clicking “Hide completed items” above the checklist, but Trello doesn’t hide them by default. You can set this extension to click that link for you every time you open a card. Your completed items don’t go anywhere, just click “Show checked items” to see them again. They’ll be hidden the next time you open the card.

Show or Hide Card Label Text

In list view, card labels are shown as a strip of colour. If you have given the label a name, this can also be displayed. This was always a hidden feature in Trello, and lately it appears Trello has removed this functionality. This option brings it back — switch it on display card label text, switch it off to hide it.

Place Cursor in Two Factor Auth Field

If you have two factor authentication enabled, this option will place the cursor in the field when it appears.

Very useful to make the comments section of a card clear enough to focus on what really matters. Great job.
