Ive had the app for awhile now, and it is by far still the best mobile sketch app as of right now. However, your newest update almost changed that.
Heres the new updates problems:
1) When I want to place and delete a background picture for tracing purposes, Im no longer able to delete it. This makes it impossible to modify already existing drawings.
2) This hasnt happened yet, but from what I can tell, people have been accidentally deleting their hard work because of your inconvenient trash can. That has to be fixed.
Heres the things I disliked before the update:
1) Zooming in and out would cause marks on the sketch. Erasing my hard work was frustrating and tedious.
2) Your lack of a filling can made me spend hours filling in areas manually when they couldve been done instantly. Its much harder to trust your hand with coloring inside the lines than it is with an auto tool.
3) No matter what I tried, your tools would never allow me to get a perfect shading. The closest thing I could find was the spray can, and even then the work would look uneven.
Instead of ruining the app for a better look, you should focus on helping the people who use it. That may seem like a foreign concept, but I assure you, people will be more willing to get this app if it actually meets their needs and gives them an easy and convenient landscape to express themselves. Because to me, it feels like my ideas are bigger than your page.
