Forked from [[User:Alex Smotrov/histcomb.js]]
histcomb = history combiner?
From the documentation page at [[User talk:Alex Smotrov/histcomb.js]]:
Script improves readability of history pages
- Consequent edits by the same user are folded together
- Size is replaced with difference (like in watchlist/recent changes)
- "Talk", "contribs" and "undo" are shortened to one letter
- Your edits are marked with light green background
- Link «Contributors» under heading goes to useful toolserver tool.
Changes by Novem Linguae since he forked it on 2023-01-22:
- refactoring
-
