This functionality is already completely implemented in core Obsidian.
In global search, type two double quotes "" to search for empty string. This matches every file in a vault.
“Portion of the vault” is vague specification but maybe “path:” search operator is what you are looking for.
Sorting by creation/modification date can be done by ↑↓ icon above search input box.
There are also icons to modify amount of displayed content or to copy sorted list of filenames into clipboard.
In order to use it as additional plugin which does not require to close another opened list of search results, consider supporting request Allow Multiple search panes at the same time
I say it all the time: filesystem metadata can be transitory over time, a victim of migrations and conversions. It’s best to put it in the file name if it needs to be permanent.
The idea that comes to my is using a spiral plot, where then length of the spiral represent time. It could be a variation of the current cloud plot that shows interconnection between notes (objects dimension) versus a chronology (time dimensions).
The inner part of the spiral contains the older notes; the newer are on the outer side of the spiral.
Would it be worth it to show links between notes across the timeline? I would look very confusing and crowded. But it would focus of activity in time.
