I'm an artist, and soak up features like a sponge. For me, features and tools offer the chance to do more, and to do it better.
Simplifying things as much as tablets often do ruins everything for me.
Bells and whistles are so very important, and they're fun to learn.
But to answer your question, I'll try to help. Although I'm new to this program, here is what I think may help:
-----> From the main screen, select the Pencil Tool from the tool icons on the left-hand side. It's the second tool down from the Crop Tool.
-----> Next, down at the bottom, between the Color Square and the Size Slider, tap on the little mini pic with a number under it.
------------> This will bring up the Brush Editor.
-----> In the Brush Editor, near the bottom of the dialog box, tap on the ^ (up arrow) by the current group.
------------> Select "Inking."
------------> You'll see about eleven pen choices. Many of them are very smooth.
If you want to modify the settings of whichever pen you select, you can bring up a list of setting categories by tapping the Slider Icon while still in the Brush Editor dialog box.
------------> It's in the upper right corner of this dialog box.
Now, you'll see a list of categories. Inside each category, there is a list of various choices for you to experiment with.
Have fun!!!
