Powershell Studio Project

I am looking for someone to help me with a powershell Studio 2025 Project.
I am learning for to use this platform and powershell in general.
I need somone who will take some time to show me what i need to learn on a add hock ongoing basis.
I have created a little project that i have attached to this project.
I want to be able to add to this project as time goes on
so basically it will have a ever growing list of check boxes each one will do something (for eample, 1 would open notepad, 1 would run some powershell script etc etc)
i want to be able to put a tick in the boxes of what i want to run, so as an example if check box 1 and 3 were checked when the "GO" button is presses, it would action these in order.
I also need the selected boxes to write to the richtxt box as an example if 1 whas checked
it would output
Opening Notepad
it would then run the code to open notepad then it would show
Notepad Opened

doing this in turn for all selected tasks

when all has run it would write

all tasks completed and wait 15 seconts befor clearing the screen and displaying "Ready..."

Hope I Have explained myself but can talk further about it

Here is the dropbox link to the project i have created and need help with
