Queue sending message after file upload finishes
#21,264 opened on Oct 6, 2022
Description
The Problem to Solve
Observed: When a user pastes an image and hits ENTER immediately, then ENTER is ignored because the file has to upload and process first.
User story: https://community-daily.mattermost.com/core/pl/4xswkr8zbpdabesft54c3i7m5h
Below is an example of trying to hit enter before a file is uploaded: Hitting ENTER while a file is still uploading removes focus from the input box until the user types any other character (to refocus the text box), then hits enter again to send the message (after the upload is complete).
Proposed Solution
If a file is still uploading while a use tries to send their message, the message posts to the channel in a ‘pending’ state (greyed out) with the file attachments showing their upload progress. The pending message should maintain it’s position in the post list if other messages are received or sent before the attachment finishes uploading and the message.
