Hi Sunny Alan, welcome to the forum.
I often make use of the DualISO function, which essentially takes a picture with two different iso, in order to improve the dynamic range of the picture. It's a bit like HDR bracketing, but without all the downsides. I make use of it in order to have greater control over the picture once I correct them.
Another feature is the bulbtimer. In this series I don't make use of it, but usually you can only dial the exposure time up to 30 sec. on the camera. The bulbtimer however allows you to crank it up to any value you want. Especially at night or with strong nd filters, exposure times of 1 or two minutes are thereby very easy to achieve.
Another function I very often make use of is the intervalometer. Usually, external devices are used in order to do this, but with ML you can save that money. The intervalometer allows me to take startrails very easy. Also, I can take a series of pictures and stack them in a subsequent step. That way I can make a long exposure of a stack of images, which is a cheap alternative to a strong ND filter. The picture "Dingle #11" demonstrates a result of this technique. It's a stacking of 22 exposures of 1.3 sec. each.
