Hello can anyone create a free showcase extension , means we have seen many times that when we open any app for the first time it showcases its functionalities means it shows which button is for what purpose , Hope so you have got it . Thanks in advance , its a humble , keen request for all the extension developers
Here you can find a showcase extension. It costs 15 dollars
Sometime things are just not free.
What the others really meant is that there is no free showcase extension currently available. That is why they posted links of existing extensions.
