I have bought a template from Templateify called Amalia/link/button. It costed around US$6.95, it's 55 in HKD. That's a reasonable price for me to transform my blog.
It contains the main feature that I concerned about, which is the drop down menu. 

It is really hard to organise your post if you don't have one. Therefore, I got rid of the official templates which  don't support this feature.

With the help of my boyfriend, who is a programmer, I finally get this decent template finished.

If you think the price is not worth it, feel free to use their free one. You can still get what you need from that free license. Also, if you feel not safe to pay with your credit card, I recommend that you use a debit card for it. Some blogger have reported scam from buying templates. 

The other feature that I appreciate, is the short code feature. It provides decent buttons and boxes for you to use easily.
