simply put, i think dota needs an option where you can favorite a certain part of a replay and be able to access it. i think this can be implemented using the "copy to clipboard" function in the replay. then that saved time from the replay can be accessed via the Watch tab.

for example someone could easily open the watch tab and have another sub -tab called : favorite replays or parts of replays. and then by clicking on it the replay would open and jump directly to that part.

i believe this would be very helpful in analyzing key parts of a match and easily refering to them.
