I frequently have to relink media. Sometimes many times in one sequence or project - and there are 2 very amateur and annoying bugs:
1 - the relink media directory never remembers where you left off, even if you were just there 1 second ago. So your left clicking through the same directory over and over again just to get back into the folders where you left off to relink to media, just a moment ago. When you have to do this 10, 15, 20 times in a project in an edit session, you can see how annoying and time consuming this can be for a professional editor on a time crunch.
2 - If you select a bunch of missing clips on a timeline to relink to, i.e., and only one isn't found, you have to start over entirely....because it won't let you SKIP a clip in the batch. You are left having to go back and drop the clips you just relinked only to relink them again, (which takes even more time - see #1) this time leaving the 'missing' clip out.
