# History

The card history side panel is the central hub for seeing all card changes that ever happened to a card. Access it by clicking the history button to the right side of an opened card.

## Timeline

The history panel contains a timeline listing in detail all the changes to a card, including changes to:

- Title and text
- Priority
- Effort
- Owner
- Deck
- Due date
- Checklists
- Sub Cards
- Attachments
- Runs
- Milestones
- Tags
- Dependencies
- Workflow state
- Conversations

If you are using time tracking, it also contains time tracking related entries as well as a time tracking summary at the top.

You can use the filters at the top to focus on specific kind of entries.

## Created by

You can scroll down the history timeline to find the initial card creation properties including who assigned them. For a quick glance for who created the card at what date, you may also check the dedicated _created_ table at the top.

## Watching a card

An eye icon among the status icons of an opened card shows that you are watching it. To start or stop watching, use **Watch Card** or **Unwatch Card** in the card's [More Options (…) menu](https://manual.codecks.io/quick-settings/#the-more-options-menu). The list of other watchers isn't shown. Watchers get notified about important updates like workflow state changes or new conversations. See [notifications](https://manual.codecks.io/notifications/#watching-cards) for what watching a card means in detail.
