Feature: Option to remember files

[dschier-wtd]

Hi, thank you for the effort and work done here.

I am a very happy user of Marker and wanted to ask, if the below feature may be added.

For now, we can add a sidebar to see currently open files.

It would be awesome to extend on this feature and show one or all of the below optional, but permamently:

• recent files
• bookmarked files
• all files from a specific directory

This would ease the access to commonly used files like Notes or Files one is currently working on.
