I think the icons theme on Tryton to require a new design and current it is not unified with the web client (sao), because this use another theme, when the end users switch from desktop version to the web version are confused, because the icons are completely different, this show UX design problems and integrations between versions desktop/web.
- To create a new unified and nice theme icons for Tryton.
- Using the exactly the same icons in web and sao version.
- Maybe to use to crowfunding campaign for to pay a professional UX designer for that Tryton have its own icon theme.
- Choose best style for start design process using a survey between community
This is an example style ideas (but I hope another proposals from community):
