I have indicator which is needed to change

present the indicator consists of two functions. one retracement function shows the fibo retracement of some move, the second function finds the largest correction in the move, marks ABCD waves, gives the size of the correction in pips and makes a projection of this correction from the top or bottom depending on whether there is an upward or downward wave.

i need change panel to starting this indicator. at present it is hard to use. changies are below

1. panel needs to be changed. there should be buttons. after pressing the button, you will have to mark 2 points on the chart. concep of indicator is in attachement
   
2. it is needed to improve the removal of elements from the graph. now it is so that either some elements remain on the chart or you have to click somewhere so that the elements that were supposed to disappear disappear
3. it is needed add letter D at the end of CD wave. now there is ABC and there is no D
4. it is needed to improve retracement and correction operation. the point is that if I move it to another place, it should also work
5. the indicator is supposed to react to the price change. I don't know if it's enabled at the moment. I will check. the point is that when the price makes a new high/low, the endpoint should update
