Improvements to drawing tools (mobile)

Could we have the options to delete drawing tools from the chart itself? I have alot of trend lines on my chart and if I want to delete any its a guessing game which I'm going to delete. We need the option like in tradingview to click the trend line and alter its features without having to drop back into the drawing screen. It only really works well for the last line you place. Ability to lock lines too or only drag them after you press them once? It's so easy to drag them by mistake when pinching to zoom etc Freehand scribble would be handy too.
