I have some suggestions.

When you're watching an replay and you press ESC, it goes to the main page instead of going back to the replays folder, so if you want to watch another replay you need to go to the main page and press the replays option again. It would be cool if it redirects you back directly to the replays folder.

I saw I can't delete a folder is there's a replay inside it, so I have to delete all the replays first and then delete the folder. Would be a cool thing to give an option to delete the folder even if there's replays inside it, then the replays would go back to the main replays page.

I don't know if it's possible but it would be cool to have immediate replays result when you're searching for one instead of typing the name of the replay and then pressing "search". So if you type "MA" it will immediately show you the "Mack" replays, no need to press the "seach" button.

A "Move to folder..." button for each replay would be cool too.

Also, I saw I can't use the number keypad of my keyboard to name the folders and replays.

I'll edit this post if I have any other suggestion
