the seed more than 12 words.

The seed electrum chose itself is 12 words, and I tried the seed more than 12 words, say 24 word, even 48 words, they work too. Electrum now support the seed more than 12 words? Does that means the more word we use (choosing randomly), the more difficulty to brute force attack, the more safety we get? 48>24>12 ?

Yes.

But another consideration:

Yes.

But another consideration:

So, should I create a 24 (or more) words seed to use?  will it be supported in the future version?

And thank you!

Not recommended at the moment. You can use arbitrary length seeds starting from Electrum version 2.0
