Feature Request: Please support the Scintilla split view feature

[KalleRosswald]

Hello Developers,

in recognition of your design preferences to create a single window editor, I would like to make the following request.

Is it possible to support the split-view feature of Scintilla? Scintilla offers its own functions for multiple views of the same document. You can easily create a second Scintilla control and link it to an already opened file using the Scintilla Document Pointer.

The editor would still offer only one window to view and edit one single file at a time, but you would be able to work on different parts of the text without scrolling.

The splitview could, for example, consist of two Scintilla controls, which could be placed below or next to each other.

Thank you for the hard work on Notepad3, I like it already so much.

Greetings Karl
