Add redo and undo button on markdown phase

Components

Utopian is a platform that works under the decentralized community which is steemit. As far back as 3 weeks now after stumbling on utopian, i noticed its a world-spanning community of enthusiasts and volunteers, working together on thousands of cool projects. Utopian.io rewards you for making contributions to Open Source projects, like fixing bugs, translating texts, writing documentation or sharing good ideas and more

Proposal

After so much time using this platform, I noticed there are some features which are important but are missing on the markdown header section, they are

• undo button
• redo button

This feature can be seen on WordPress

This component should be modified into utopian. Why? It allows users to undo certain mistakes and reclaim some unintentionally deleted words when using the text section.

Mockups / Examples

Here is a sample of how the feature be added and where it should be added provided it's applicable

Benefits

• As the name implies; undo will allow you to delete unwanted texts when using the text editor section and;
• Redo will allow you to redo a certain command if there's a situation of unintentionally deleted/removed texts
• It saves time when typing and editing
• It gives way to professionalism in typing
