How can I highlight the significance the last item in my list of examples?

I am in the middle of writing a paper, and I want to highlight the importance of "learning" in the following sentence.

Nowadays, we use our mobile phones for different purposes: communicating with friends and relatives, transportation, shopping, and learning.

Is there any way to attract readers' attention to learning in this list of examples?

To be honest, I was thinking about saying "and more prominently learning", or something like that but then I think that the most prominent application of mobile phones is for communication. Any suggestions for me? Thank you

The expression "not least" is useful to single out the term that follow it as special, important, noteworthy.

Nowadays, we use our mobile phones for different purposes: communicating with friends and relatives, transportation, shopping, and not least, learning.

(FreeDictionary) not least notably; in particular.

In your particular case, since the element you wish to emphasise is the last on your list, it is common to use the expression last but not least, which means:

importantly, despite being mentioned after everyone else; despite being mentioned at the end:

I would like to thank my publisher, my editor, and , last but not least, my husband.(Cambridge)

You can use it as an aside, between commas (before last and after least), or only with one comma after least:

The television is big, has an excellent picture, and last but not least, it's cheap.(M-W)

You could set traditional use(s) apart from newer ones, and emphasize the last with an adverb, something like:

Nowadays, we use our mobile phones not only for communicating with friends and relatives, but also for transportation, shopping, and especially/particularly learning.

(or .... and learning in particular.)
