Hey Peter,

Well, it indeed is kind off a taste thing yeah.  
For complex statements, i would advise to use the “normal” IF, THEN, ELSE and END IF cards.

The thought after IF-THEN and IF-ELSE-THEN (and i am creating a ELSE-THEN) cards, is “single line” statements.

[IF-THEN statements | Homey](https://homey.app/nl-nl/flow/AivzYx/)

When you fill a string/text with a lott of **possible values** , it usually means a lott of single-line-statements, like this:  
IF vaccuumbin is Full THEN str = str + “Bin is full!”

If you program block-statements, you need 5 cards for this.

- IF
- condition
- THEN
- execution
- END IF

This just felt wrong to me, because i would be using this a lott (programming single-line IF-THEN statements.

With the IF-THEN, you just need 3 cards:

- IF the next 1 card is true, execute the next 1 card
- condition
- execution

And when i made it, i thought: why would i fix it to The next card and the Card after that?  
So i bould it so you can set the the amount If/Then cards yourself 🙂 Its just more flexable that way.

In big string-collection flows, these IF-THEN and IF-ELSE-THEN cards are a real space-saver and therefor performance-saver (on the Homey mobile App anyway).

But for any other use then simple IF-THEN (string) collection flows, i would advise to use the IF and THEN cards, as, indeed, this is more clearly readable and less error prone.
