Suggestions for the pen and eraser

Alright, I wanna be able to do more with the pen, um and alike an auto past for all the pages, it would help me and an easy way to delete frames, there can be a select option and you can secrecies multiple frames and push a button. Also, I kinda want new brushes maybe like one that’s super fine and thin, and one that’s thick and big, one could be messy.. IDK.
