ICON at Top for Dual-Pane (Edit+Preview)
Something like this icon:
[
]
Or something like:
[
]
Or
[
]
Would make sure the current file has 2 vertical panes of equal width OPENED immediately:
Edit Pane (on the left)
Preview Pane (on the right)
THIS WOULD APPLY FOR THE CURRENT FILE WHICH HAS THE FOCUS and/or ACTIVE CURSOR in.
Many best apps on: Windows, Mac, Linux and even Android (Epsilon) have this Daul-Pane launch of EDIT+PREVIEW.
This enables live preview of WYSIWYG of markdown files.
Crucial for fast blog posting.
I know we can vertically split windows and open second one and switch mode.
But this is not clever regarding the extra number of UI steps needed, and amateurish UX.
When it can so easily be coded.
This icon would be next to PREVIEW icon at top-right (when in Edit Mode).
This icon would be next to EDIT icon at top-right (when in Preview Mode).
This post is for the attention of devs and/or managers only.
Thanks for the great app and best wishes.
