I appreciate the different features to edit the documents. I primarily used it for my studies, where I have to closely read a large amount of texts and am not always able or willing to print them (also due to ecological reasons).
However something that annoyed me somewhat is the fact, that one can not edit the font of individual words in a textbox. For example when I want to underline a specific word in a sentence, it automatically underlines the whole passage.

I chatted with two reps for over an hour each with no results. I then chatted with KARA and in less than five mins my problems were solved. Kara is earning her pay cheque, she is a true asset to this company. YOU NEED YO PAY HER MORE MONEY.

How is the universe fine-tuned for life?
The characterization of the universe as finely tuned suggests that the occurrence of life in the Universe is very sensitive to the values of certain fundamental physical constants and that the observed values are, for some reason, improbable.
Can you give some examples of the fine-tuning of the universe?
So, in fact, we wouldn't be living here at Allie wouldn't exist. Examples of such fine-tuning abound. Tweak the charge on an electron, for instance, or change the strength of the gravitational force or the strong nuclear force just a smidgen, and the universe would look very different, and likely be lifeless.

What is fine-tuning in physics?
In theoretical physics, fine-tuning is the process in which parameters of a model must be adjusted very precisely in order to fit with certain observations. The heuristic rule that parameters in a fundamental physical theory should not be too fine-tuned is called naturalness.
What is the anthropic universe theory?
Anthropic principle. The anthropic principle is a philosophical consideration that any data we collect about the universe is filtered by the fact that, in order for it to be observable in the first place, it must be compatible with the conscious and sapient life that observes it.
How many cosmological constants are there?
Image credit: Particle Data Group / LBL / DOE / NSF, of the Fundamental Constants as of 1986. As it turns out, it takes 26 dimensionless constants to describe the Universe as simply and completely as possible, which is quite a small number, but not necessarily as small as we like.
What is fine-tuning in philosophy?
The term fine-tuning is used to characterize sensitive dependence of facts or properties on the values of certain parameters. Technological devices are paradigmatic examples of fine-tuning.
How do you use fine tune in a sentence?
fine-tune the process for industry by investigating how specific properties affect performance. Fine-tune the images yourself using the easy control panel. Fine-tune the product. Fine-tune the policy, the danger is that the most valuable provision risks being squeezed out.
