Adding an NEW icon for "Open Document White"

[999px]

Adding an icon for "Open Document White" to the ToolBar (you can also add a hotkey)

Although it would be ideal to be able to add IMMEDIATELY icons of third-party programs for opening an open document in them.

For example, when editing MarkDown, I use a program for viewing these files and it would be convenient to be able to quickly call this program.

There is "Execute Document" (for Tools -> Execute Document) in "Customize Toolbar" (right click on toolbar).

"Execute Document" is different.

Here is a real example: By default (when double-clicking on a file) markdown files (.md) are opened in Notepad 4.

So if I click on "Execute Document" in notepad 4 for .md files then ... nothing will happen.

And via "Open With..." I can choose a program. (Personally, I use Markdown Universal Viewer with a viewing plugin for viewing.)

Could you please add the ability to add an "Open Document With..." icon to the Toolbar?
