Client feedback arrives as emails, chat messages and call notes: at 0:42 the music is too loud, the second shot feels long. Without a system, points are lost, repeated, or contradict each other.
Collect everything in one list
Paste every source into one place and sort by time. Notes written as 0:42 or 1:05-1:12 can be turned into a single change list with checkboxes, so nothing depends on memory.

Timecode Notes turns client notes with times into one sorted change list. Product page
Tie every note to a version
A comment on v1 may no longer apply to v3. List your versions and check which notes name no version, or the wrong one. Ask the client one short question instead of guessing.

Video Version Check lists notes that name no version or the wrong one. Product page
Re-cutting moves the times
After you trim, insert or change speed, old timecodes point to the wrong place. Recalculate them from your list of cuts instead of correcting each by eye.

Marker Remap recalculates old comment times after a re-cut. Product page
Spot contradictions early
Two people may ask for opposite things. List requests by person, find the conflicts, and send one clarification message before you start editing.
Keep scope and revisions visible
Record the agreed deliverables and the number of revision rounds included. Log each later request as in scope, extra or declined. A short record the client can read is easier than an argument.

Scope Ledger records deliverables and logs each later request. Product page
Close each round
Give every request an outcome (done, partly done, declined, needs an answer), then send a report of what was done and what remains. It protects both sides.

Revision Closeout gives every request an outcome and builds a closing report. Product page
