Hello,
cli tool is not user's compliant :)
Users should be able to delete (not just deactivate) their datas without any admin intervention.

Right now, only mattermost instance admin can export teams but only all teams.
There is two issues:

• first: we can't export one team (see this request: https://mattermost.uservoice.com/forums/306457-general/suggestions/39225376-mattermost-bulk-export-single-selected-team)


• second: it's the instance admin job to export

It would be a great improvement if team admin could use the user interface (and not has to ask to his instance admin).

Allow GIF picture as personal picture avatar

Currently only BMP, JPG and PNG are supported (message: Upload a picture in BMP, JPG or PNG format. Maximum file size: 50MB)

I'm currently using Mattermost Version: 5.24.2

Right now mattermost provides statistics at App level and at Team level. It would be really helpful if admins can see stats of different public/private channels too.

That means if I have 15 different channels, I can stats of all of them and pick which one is being used the most and which is least.

What do you think guys?

To have the ability to post messages which will automatically disappear in a certain time set by the sender.

Be able to see thumbnail images and a small description when adding a link. As WhatsApp, Signal and Telegram do

I have not found any way to specify the Postgres schema that mattermost should use and saw that the "public" schema was in the sql migration files.

Using the public schema is not a recommended practice with postgres : https://wiki.postgresql.org/wiki/DatabaseSchemaRecommendationsforan_Application

See first section stating :
"The recommendation is to create a single database with multiple named schemas [...]. Additionally, it is recommended to remove the public schema."

Hallo,

as Admin on Server, i need options to delete Users,Teams,Channel, History of Posts from "System Console.

Thanks

Ability to use a generic 3rd party OAuth server for programmatic logins to mattermost server (team edition)

Please see for detailed description:
https://github.com/mattermost/mattermost-server/issues/14293

Mattermost currently lacks some feature of Slack app

1. Block Kit is a UI framework for Slack apps


2. Shortcuts give users clear entry points to access your app, can trigger modals and other app interactions


3. App Home is a private, one-to-one space in Slack shared by the user and the app, within any App Home, there are multiple tabs, Some tabs like About And Messages are fixed, but Home tabs can be fully customized by apps

these feature can improve Mattermost plugins user experience

The use case is to provide information to users, for example, release notes, status updates, etc. In order to keep the channel relevant and to avoid clutter, non-admin users have read-only access.

This feature allows a team to create "reference" channels.

1. team admins: create, read, update, delete


2. non-admin users: read-only

This idea is similar to, and currently under review for Enterprise Edition:

This idea is related to:

A simple image editor for uploaded images. This to draw lines, write text and add arrows. Would be great when explaining things. As in a quick bug report.

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.

Please add the team name to any notification emails sent by MM. While we have few teams with common channel names, it is really confusing from email body which team it is.

I was receiving a generic "Received invalid response from the server" messages when trying to upload the BigBlueButton plugin. I eventually discovered that it was because the Maximum File Size was configured to 5MB.

A clear message stating either what the "invalid response" was or flagging the issue as "too large of a file" size would be less generic and easier to troubleshoot.

When there are multiple teams, when a new post is made to another team, it is difficult for users to notice it. I want you to show it with an impact that would reverse the color information of the icon.
The same can be said for the channel name display within each team. It is difficult to understand with the current bold display.

Summary
At the moment, it is only possible to use root of the bucket. It will be nice to be able to use subfolder of the bucket. Some of us have more than 50 buckets...adding even single one more is chaos.

Expected behavior
Be able to set S3Prefix in order to use s3://bucketname/s3prefix/s3_object
