Improve existing line drawing indicator

Hello all, In attached files you will find my existing indicator.

All the initial aesthetic settings for line type/thickness selection must not be changed.

This indicator already works very well, it allows you to draw lines manually. What is required is an improvement in the use.

The objective of my request :

1. The drawn line should always be ONLY on the timeframe on which the line was drawn. This means that for each timeframe the user will have his own drawn lines.

Example: If I draw the line on H4, it must stays and only be on H4, not on others timeframes (M15, H1, etc...).

2. Currently to draw a line, it is necessary to make a "fast" double-click, this action should be modified to have the following sequence: 

1.1) Activate the possibility of drawing a line by pressing a button on the keyboard that is set in the options of the indicator.

OR (but you can do the both - I will really appreciate that)

1.2)Activate the possibility to draw a line by clicking on a text in the upper right-hand corner of the graph. The text should show the status "ON" and "OFF".

ON: Drawing is activated

OFF: Drawing is deactivated.

2) Click once with the left mouse button to make the line to be drawn appear.

3) To have the possibility to move the line - as it described the attached video ("indicator-mouseclick.zip") with the mouse before validation.

4) Click once with the left mouse button to validate the position and fix the line drawing.

The source code of the modified indicator - validated by the applicant "me", will have to be provided by the developer.

Good luck to all.

Please do not hesitate to contact me if you have any questions.
