Have a button in the code block to copy it on clipboard

Allow emojis to be used in a channel name.

I would like to be able to see a preview of the attached image even if I am in Compact Message Display Mode.
Currently, even if the Account Settings > Display > Default appearance of image previews is set to Expanded, the image is only displayed as an attachment icon when Account Settings > Display > Message Display is set to Compact. These two settings should work independently of each other.

The Mattermost desktop client should automatically check for updates and prompt the user to update. This feature is mandatory in today's security landscape, even for an Electron app.

Most of our users don't realize their desktop is many version out of date, with pending security fixes.

Bonus points for shipping builds via the Windows Store, macOS App Store, snapcraft, etc.

As of now, we do not have a clear warning message to indicate that a desktop client has compatibility issue (old version) with the latest Mattermost Server version.

it will be a good idea to have a message (pop up) that detects the desktop client version and remind them to upgrade it to the latest version if it is at least 1.x version behind the current one.

Currently, spell checking is always enabled and cannot be disabled.

To some users, the red underlining is visually distracting. Also, the spell checker is currently unable to detect on-the-fly, in-sentence language switching, which is sometimes used in mixed-language teams or when discussing mixed-language subjects (like programming).

Therefore, I'd like to suggest adding an option to permanently disable spell checking - either in the configuration, or, in the input bar's context menu, where the spell check language is usually selected.

In the input bar it could look like this:

Having bad admins that make errors during the creation of certificates is silly. However, not being able to override their silly mistakes while they fail to address the issue over the course of months is aggravating. Although the issue will be eventually addressed, every time I open up mattermost, I get an invalid certificate error which I have to manually dismiss. I would really like to dismiss this permanently so that I don't have to deal with the extra 3 clicks every time I open up the application.

I consider it unacceptable that I can't choose to disable having my words replaced with emoji, without also having to give up on EVERY SINGLE post formatting feature. I want to be able to use post formatting, just NOT have any emoji appear without me explicitly choosing to insert them.

Bitte einen Build (Installationspaket) für Windows on ARM64 zusätzlich.

When updating existing installations of Mattermost with the MSI, the desktop app should automatically restart if it was running when the installation started. At the very least, the installer option that starts Mattermost after installation should be exposed as a public property, so it can be set as a switch when installing with msiexec.

Currently, the MSI kills the process but it doesn't restart when running with the /qn switch.

Hi,
Since the Mattermost Desktop client does not include an auto-updater and the iOS version is already distributed on the App Store, why don't you distribute the mac client on the Mac App Store.

This would solve the updating problem and also make the app easier to discover. The download page is pretty hidden on the mattermost website, I always end up on the server download page when I only want to check for update.

Currently you have to know and type the exact name when searching in a direct message history of a single person via "in:@name". Whatever you type is even falsely "corrected" to some other channel when there is a match and you hit enter!

That is why I suggest to include member names in the suggestions when typing a name with "in:@...".

There should be a 'Buzz' to alert the other user. Like, Spark, Yahoo.

Sometimes we have messaged to another user. But user is busy on another task. He/She missed the messages which is very important.

In this case, the user should have a 'Buzz' button or shortcut for alert to someone. I hope everyone knows about the importance of 'Buzz'. :)

File upload should trigger a modal to be shown in which user can add more files and also enter corresponding text against the image upload.
I would like to help in implementing this feature.

Currently tons of space is being wasted in the sidebar. Allow for tighter spacing of channel/user names so more of the list can be displayed at once.

Add the ability to Collapse a post containing markup. Just like you can already do with a image.
