Several minor practical improvements

[KydoxOwn]

1. The ability to apply custom colors to text, backgrounds, icons, and tags (like those in tables). Currently, there is a limited selection of colors, but for greater flexibility and freedom, it would be great if users could create their own colors using color codes or a color picker. You can also customize the color of the title

2. Adding banners to documents, similar to Notion or Appflowy, would be a great way to make documents more visually appealing.

3. Currently, you can't delete all documents at once from the Recycle Bin; you can only select them one at a time. This feature should be added.

4. The selection of icons (not emojis) is very limited; it would be great to expand it, for example, by using Streamline (open-source icons) to add more options or by providing an interface for adding custom icons. And the sizes of the emojis and icons vary, which doesn't look very nice

5. Use icons and emojis in Workspace as well, not just as a background image

6. If you want to insert a divider, it’s faster to just type “—-,” but to make it even easier, it would be handy if you didn’t have to press Enter first and the line appeared immediately
