Currently it is not possible to have notifications triggered based on keywords, for example if there are any emergency keywords, a certain ringtone or vibration (or both) will be triggered.

This would be important in the event of any emergency that requires immediate action.

This has already been requested here:

https://mattermost.uservoice.com/forums/306457-general/suggestions/18607111-confirm-with-ping-warning-before-sending-all-eve

But for some reason, the confirmation has been implemented only for (at)all and (at)channel, which still allows people to use (at)here mindlessly (without realizing they're about to ping sixty or more people, for example).

So, I kindly request (at)here to be added to this list.

This would require major architectural changes for the Mattermost server, but adding some use cases to gather feedback from the community.

Server admins wouldn't be able to read the content of conversations because they don't hold the keys to decrypt, which means users wouldn't have to worry about
- Server admins spying on their private conversations
- Governments subpoening server admins into handing over conversations
- Hackers taking control of the server being able to read the conversations

Support Gitea's OAuth2 provider as an authentication source.

Currently, the team edition only supports GitLab as an OAuth2 source. GitLab is pretty heavyweight and many people prefer other software for a variety of reasons.

Gitea (https://gitea.io/en-us/) is a really nice open source, community supported Git server. They recently added support for acting as an OAuth2 provider (see https://docs.gitea.io/en-us/oauth2-provider/ for documentation). It would be great if Mattermost would support Gitea as an OAuth2 provider.

Slack recently increased their character limitation on channel names. We would like Mattermost to increase the limit as well, as this has been a helpful feature since it was rolled out.

The same way we can send messages, we should be able to send voice messages.

It should be as simple as click "add voice", record what you want, press send and it's made available on the server for others to listen.

It should be supported by browser and mobile client apps.

Allow emojis to be used in a channel name.

The docs explains that:

"IP addresses, for example 10.100.200.101, do not return results."
(https://docs.mattermost.com/help/getting-started/searching.html#hashtags)

I would like to be able to search on ip-strings from my messages.

for the default search backend (sql), search results are capped at 100!

you can verify this by loading jquery and doing:

$('.search-item__container').length;

you can see that paging isn't supported:

https://github.com/mattermost/mattermost-server/blob/master/app/post.go#L821

and the sql uses `LIMIT 100`:

https://github.com/mattermost/mattermost-server/blob/master/store/sqlstore/post_store.go#L834

i know this isn't an issue in enterprise because you're using elasticsearch, but please either bring elasticsearch to team edition or fix the default search backend. 100 results is sad :(

For threading purposes it'd be great if consecutive messages from the same person (maybe within some time window like 10 minutes) would be counted as a single message.

We use mattermost for an internal support chat and very often we get stuff like

"Hi!"
"I have this issue with the fronk, for customer Acme"
<screenshot>
"Could someone take a look?"

You can't reply to any of those messages without losing crucial information in the thread.

I would like to add a string to the header and purpose every time it is changed via a plugin, but this is currently not possible as there is no hook for channel metadata in the plugin API.

As per the documentation : https://docs.mattermost.com/deployment/sso-saml.html#saml-single-sign-on-e20 SAML currently does not support automatic deprovisioning, and is only possible if AD/LDAP sync is enabled.

For environments where AD/LDAP is not possible, it would be great if SAML could also automatically deprovision users from Mattermost as well.

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.

Something like "subscribing" to a channel, where when anyone posts in the channel, you get a direct message badge that behaves like they @'ed you for every message.

Example:
UserA: hi
UserB: sup

Windows icon on taskbar: red (2)

A user should be able to easily see & search the list of all channels they have joined and can join. I'm seeing a number of duplicate channels created across teams because the user did not know it existed in another location.

Allow plugins to add to the settings menu, much like they can add to the System Console settings.
