You cant really change alot of things in the properties panel :(( u can only change position size and rotation, u should also be able to change the opacity and stuff like that
for text objects u should be able to change the text in the properties panel (so it doesnt change for every object)
for videos u should be able to change if its playing or if it should loop
i generally just think theres alot more that can be added!! :3
thank uuu
