Solid first post, welcome on steem! However, I would suggest using a standalone vector graphics editor like Inkscape (https://inkscape.org it's free/open source). Reasons for my recommendation are: better performance, more features and the possibility of working offline. P.S.: I can imagine cases in which it is impossible to install full applications (working on a chromebook) so here is another free editor to add to your list: https://vectr.com/
