Add 3 different Trendlines to exisiting Indicator

Hi Folks,

I have an existing indicator "Color Levels" and wanted to add 4 additional buttons to the toolbar:

FEATURE 1

3 Buttons for 3 different trendlines

Adjustable Properties for the Trendlines:

a) Colour of the Trendline (Black, Blue ...)
b) Style of the Trendline (Solid, Dash, Dot...)
c) Size of the Trendline ( 1,2,3 ...)
d) Time: example: 02:30
e) Value: example: 100


FEATURE 2

1 Button for "Unselect all" - Function

Explanation:
Sometimes there are a lot of different symbols selected in the chart (Trendline, Fibonacci Retracement, Rectangle ...)
Each selected symbol has 3 small visible quads. After riight click on such a marked symobl and pressing "Unselect all",  the selection will be removed for all selected symbols.

Would be fine, if this additional function you be added to the toolbar of "Color Levels".

Not sure, whether this is possible in an indicator or in a script.

ATTACHEMENTS:

1. Find attached the indicator "Color Levels"
 (You also could download this indicator from  https://www.mql5.com/en/market/product/12215)

2. Please find attached a picture of the toolbar with additional 4 buttons

In case of any question feel free to ask.

Thanks in advance for your help.

Kind Regards
Christian
