HTML5 Canvas Add more features to my script PART 2

PART 2 - This is part 2 of this project. 1. I have text that is displayed over the canvas over video, I need to add DURATION to it. Text duration, default 10 seconds, that means that it will be displayed on the preview screen for 10 seconds only or the number of seconds we choose, i.e.: ts:3.456 te:13.456, display only 3 digits but use all the digits when adding it to the json. But we will add up down arrow to increase decrease the time. 2-Each Text addition is independent they need to have their own order, 1,2,3,4, I should be able to move them up or down so they overlay on each other (Layers). Add DELETE option, I can edit it too and it will get updated on the json. 3-I should be able to turn the TEXT left, right, bigger, smaller (RESIZER) , please add handlers - json gets updated 4-Allow text color-color picker, bold, background (color picker), type 5-Add a button to add images, png, jpeg, add the same as text, TURN (handlers), delete, NUMBER next to it (I can move it - ORDER). Default 10 seconds (I can see it for 10 seconds ) I can change the default duration. 6-Add a button to MUTE the video and add the option on json on or off 7-Add a button called Add Music, and add it like with the text but there is no DEFAULT, you will need to CUT the song/mp3 based on the duration of the video, i.e.: the video is 30 seconds, I click ADD MUSIC at 3.567 seconds then the song will stop at 30 seconds (even if the song/music is 3 minutes). Music and Sound from the video could be listened at the same time (if mute is not used).
