Why Do We need this ?

• Larger Multiline Input Elements will open new possibilities for Rocket.Chat App Developers.

• Larger input components can be used in future apps which include a Code Editing App where the developers pair program inside Rocket.Chat.

• Or a Journal App/Notes App where journal Entries or more extensive notes can be made in RC

• Or a Future GitLab integrations where a code Review and Edit feature will be desirable.

• Larger can even be used in the main chat input component to edit and send a larger message to the Rocket.Chat channel, which may not be possible with the current input component.

• Our use case and motivation to add this component to fuselage was to enable users display and merge PRs right from RocketChat channels through the GitHub App. This will be an exclusive feature which is not available in any GitHub x Messaging app intigration.

• We currently use the SectionBlock as the InputBlock is too small, but the SectionBlock looses the indentation.

• A Larger Input component can help us take fix this as it preserves indentation. This would improve community collaboration over Rocket.Chat and push Messaging x Developer Collaboration to the limits

• The Same component can also be extended to add new Issues to GitHub or A Rocket.Chat app which parses and display markdown. The possibilities can be endless.
