Screenshot Development of Mattermost User Interface
The purpose is to highlight and illustrate the best features of Mattermost user interface.
When choosing what to highlight in the screenshot, follow this order:
An end-user screenshot that best illustrates the feature.
Screenshot of System Console or other settings help text.
Screenshot of documentation.
Screenshot of a code mentioning the feature and/or Mattermost.
Setup tips
Use the Mattermost Desktop App, which has a nicer border.
Create a secondary account with [first.last]+blah@mattermost.com email address. This makes triggering notifications for yourself easier (for the screenshot). You can also use a second browser to login to the second account while taking the screenshot.
Checklist
Screen size:
Size your Mattermost Desktop App or browser to capture a screenshot approximately 900px by 640px, excluding browser navigation.
Use default 100% zoom.
Tip: Close the right-hand sidebar, and close the team sidebar by leaving all but one team.
Font size:
All text should have large enough font size so that text is easily readable.
Visuals:
Profile pictures and real people’s names should be filled out throughout the screenshot.
For the profile picture, use either normal-looking Avatars or stock photography from istockphoto.com.
Select the default "Mattermost" theme color in Account Settings > Theme.
Left-hand sidebar:
Include Favorite, Public, and Private channels on the left-hand sidebar.
Make sure that you scroll all the way to the top in the channel list on the left-hand sidebar for the screenshot.
You can have a few unreads or mentions visible, but don't include an “unread posts” indicator in the left-hand sidebar.
Favorites channel list: Include the following:
One Public channel.
One Direct Message channel with someone who is online.
One Group Direct Message channel using people with short names to avoid truncation.
Center pane:
Make the center pane one of the Favorited channels.
Make sure that the heading of the center pane is fully visible to avoid truncation.
Make the first message in the center pane fully visible right below the channel header.
Team list
Connect team names to channel names, e.g. Contributors, Developers, Toolkit, etc. to contribute to a broader overall theme and story.
E.g. could use icons of different maps, or city skylines, to indicate offices of different teams, or business units of a bank (customer service, security, research, etc.), etc.
Clarity:
Avoid showing any text with acronyms and abbreviations.
Do not show any bugs or defects.
Outline:
Ensure that the screenshot has a grey (#F7F9FA) outline in all four edges. This helps ensure the screenshot looks good against both dark and light backgrounds.
Outstanding look: Ensure that the contents of the screenshot shows the Mattermost product in the best light.
Show the feature in action.
Make sure that the screenshot is positive - give whoever is viewing it a positive emotion.
Show how the feature can be extended and customized. For instance, use custom slash commands instead of the default commands.
Sharing a screenshot
Share the original: Always share the original in .JPG or .PNG format, or pasted in a slide.
If you share screenshots in a slide with a drop shadow or other formatting, make sure the original is provided as a backup in case the user needs a different manipulation.
Share the manipulation (optional): If you're modifying screenshots using a format that can include layer or the original manipulation (e.g. Photoshop), offer the file containing modifications if you can in .PSD or .TIF format.
Recording a GIF
Use GIF Brewery to create GIFs. Ensure there are no watermarks or vendor names overlaying the GIF.
Do's and Don'ts
Don't zoom past 100% and pixelated images
When you need to show a particular part of the product, don't crop the image and zoom past 100% to show the functionality. Screenshots should be full-sized (no zoom-in, no resizing within Google Doc), potentially stored in a .TIF file. For optimal quality on Mac screenshots, see this help article.
Example of what not to do:
Do show sub-components framed in grey (#F7F9FA) background
Instead, show the sub-component at 100% zoom with a 12pt white border (so there's white space) and a grey (#F7F9FA) background with no border, so the image is neatly framed:
Don't display watermarks and vendor names on screenshots or GIFs
Example of what not to do ("Stop" and "created with gifrecorder.com" overlayed at the end of the GIF):
Don't take a screenshot at high resolution
Text is hard to read when image is reduced for sharing on blog posts, social media and possibly in slides:
Do size Mattermost to capture approximately a 900px by 640px area
This enables sharing the image in documentation, social media, and marketing content more easily.
