Scratch

There Should Be Variable Sensing, so it would be like this
[blocks] <when green flag clicked>
<change{ variable }by(1
<if> <{ variable }> = 2
<show>
<wait( 1 )secsc>
<play sound[
<end>
<stop script>
[/blocks]
so you can make a "how fast can you click the button 100 times" game

Selection Clicking
There should be a tab that says, "Image Selection Click"
and when I click that (with a sprite selected!)
the paint tab will come up (or something that looks like it) and then the little selection box comes up and you can select an area of the picture name it, and, with a mold block (see below) you can make  a keyboard with 1 sprite!

Mold Blocks/Hanger Blocks
These "Mold Blocks" will be red, and can be combined with  lots of things.
With Selection Clicking (see above) I can add a mold block into the end of the selection blocks and will make them like "onClick" or "on(insert sensing here)"
and also to make things easier ,like instead of
[blocks]
<when[ a ]key pressed>
<change x by( 10
[/blocks]
[blocks]
<when[ d ]key pressed>
<change x by( -10
[/blocks]
to
[blocks]
<when[ a ]key pressed>
<change x by( 10
when b key pressed (as an attachable unit, like wait, not a start unit like when (flag clicked)
<change x by( 10
[/blocks]
