In post on the Gradience Discord, the tool’s primary developer David Lapshin (daudix) explains: –
“Archiving the project […] will make it clear that Gradience is, well, unmaintained, and will prevent the issue tracker from being filled with duplicates asking when new release will be out/why nautilus sidebar is white.”
“And, if someone will want to maintain it one day, it can always be unarchived with a press of a button.”
