Souce control panel has a "grace period" where when files change it will turn gray for a time before actually changing, to prevent misclicks (e.g. due to refresh slowness).
In the extension log, command logging (started and output) includes the PID to enable correlation.
The too many active changes warning does not block refreshing the source control view.
When a section of the source control panel approaches the display limit (5000, triggers at 500 in a given section), (too many files) will appear in that section to indicate that files may be missing.
Staging of selected source is supported, but limited vs. the builtin implemenation as the API surface has not been marked as stable. That means;
It will only work if one instance of a given file diff is open.
Unstaging a selection is not supported.
This extension has undergone significant refactoring. While it may be a fork, it does not "follow" the builtin implementation.
IMPORTANT
