 - [x] Fix share button to use the standard icon (arrow pointing up out of a box) and dropdown menu with options to copy link to clipboard and share on social media (twitter, facebook, linkedin, etc.). The copied link should include a URL query parameter to link to the specific event on the map, and the map should automatically open the popup for that event when the page is loaded with that query parameter.
 - [x] Fix popup color background in dark mode (currently too close to the sea color, making it hard to visually separate from the map)
 - [x] Move the light/dark mode toggle to an easily accessible place in the UI, such as the top right corner of the map, instead of being hidden in the side panel.
+- [ ] Show activities in the event details (e.g. workshops, talks, etc.) if that information is provided by the event organizers.
 - [ ] Have the action add a comment on the issue when the data is not valid, with friendly human readable error messages to help the user fix the issue. For example, if the date format is invalid, it should say "The date format is invalid (found: `Wed 15th`). Please use `YYYY-MM-DD` format." or something similar. Make a list of all the possible validation errors and the corresponding error messages to show to the user. The comment should format the feedback in a clear and easy to understand way, and also include instructions on how to fix the errors. If multiple errors are found, list them all in the same comment in a clear and organized way (e.g. using bullet points or a table).
 - [ ] Fix the Review checklist to account for the new TBD date/time/location and online event features.
 - [ ] Add a "Submitted by" field to the event details, showing the github account url of the user who submitted the event. This can be automatically added in the workflow when a new PR is created for the event, by getting the github username from the issue that triggered the workflow and adding it to the event data.
