Assume I have (simplified) the following addresses with BTCs on it

111111 with 0.100 BTC
222222 with 0.200 BTC
333333 with 0.300 BTC
444444 with 0.400 BTC

Now I want to send someone 0.280 BTC.

I go to "Send" tab fill in the target address and amount and click "Pay".
Now Electrum decides automatically from which of my addresses the BTCs are taken.

As far as I can see it always the addresses with the biggest amount. Here 444444.

Why ?

Why not properly do I cleanup and take the money from addresses 111111 and 222222?
If always the biggest amount addresses are taken then users will end up with thousands addresses with micro amounts.

Can I somehow tell Electrum to use another addresses selection strategy?
Or even select the input addresses manually?

Sorry for this newbie question.
