Free for Windows
Revisions arrive by email and the edit happens somewhere else. You read the list, carry it in your head back to the timeline, and the subtitle at 2:14 survives the trip while the end-card logo size does not. Reopening the list costs a window switch every time. WindowPin pins that list onto the editing window, and it moves whenever the window does.
No installer · a single executable · touches nothing in the registry · v2.6.0
Turn the feedback into a checklist note stuck to the editing window. Tick items off as you finish them and the remaining count stays visible, so you are not re-reading the email before delivery. Finished items can be hidden.
Give the rough cut, the graded version and the client review copy different coloured index labels. Overwriting the wrong file usually starts with mistaking one window for another.
Label the explorer window, the browser tab list or the font picker with something like "source for this project". Minimise it and bring it back: the label follows, and clicking the label switches you to that window.
Will a note show over a full-screen preview?
Only if you switch that note to always-on-top. Otherwise it sits just above its target window and stays out of the way of everything else.
Does it slow down a render?
When the target window is not moving the watcher backs off on its own. Most of the time the app is doing nothing at all.
