Pen colour automatically changes in shape tool if pen colour is changed in ball pen.

example: I want to write with black ball pen but underline (using shape tool) using red colour. If I change my pen colour to black while writing and want to underline in red then my shape tool also shows black colour and I have to again change it to red.

please add a feature where the ball pen has a tip sharpness, i dislike the way it looks and enjoy that more rigid writing style without the added pressure, such as the fountain pen

In this respect notability feature is quite awesome…..so humble request to GoodNotes tm please do provide us the same feature in GoodNotes so that we can switch between pens of different colour like in notability,onenote,etc….

I second this. Fortunately I can find this in the feedback.
After Notability added this feature, it is simply not possible to forget that this feature can exist.
This would really help with using multiple pen colors (more than 3), especially in split screen where the color toolbar isn't easily accessible.

Or at least, don't close the little box so if I change pen colour, I need to reopen it to change the width! every time I change, it's like i have to do it twice!

Yes, that's exactly what I need. I use the program to jot down my lectures and my professors are rather fast talkers most of the time. I would love to have the option to switch between pens with ease, hence it takes too much time to do so yet. If I want to have pretty notes, I need to rewrite my notes at home and that sucks even with tea and a lit candle. Thanks.

Please allow users to add multiple pen combos to the toolbar up top (like one note allows you to do on the iPad version). I switch often between colors and thicknesses of pens and it would be much more efficient if I could simply add it as a "quick pen". See attached photo for sample.

For the jot touch , it would be better if one of the buttons switch between highlighter and pen to make note taking easier.
