InkScape is workable as a graphics design tool but it's definitely a lot clunkier to work with than the commercial alternatives, like they just coded it in a vacuum and never tested and compared with any of the competition.

some of the default in InkScape don't make a whole lot of sense, such as all the Live Preview and Apply buttons everywhere. in commercial products, everything is always live and applied on the fly, which helps a lot because you can just play around with the controls until you get the result you want. InkScape sort of expects you to already know what you want and which settings you need for that. it's not fully WYSIWYG. the way you edit filters is also pretty nuts compared to the alternatives. i never understood why FOSS apps insist on being so weird about everything. don't they know what UI expectations users coming from commercial tools have?
