Inserting "design parts" into the channel list and chat screen

If we can insert "design parts" such as separators into the channel list and chat screen, it will expand the range of the layout.

[Channel List]

1,Separator
Separators can be inserted between channels.
2,Frame
Can be used to group channels together.
3,Ruled line
It can show the relationship between channels.

[Chat Screen]

1,Separator
Separator between messages. When you create a rule or guideline channel, you can make the layout easier to read.
2,Margin
Spacing between messages. This can improve the situation where a series of messages are hard to see.

The above design parts are just examples.
