@MacToddb thank you for your recommendation, I'll think about using some common style for all apps but they are intended for different audience so I'm not sure it's ok to use the same "style".
@SFCArcher, I'm happy to know you appreciate the app.
Here is another (and probably the last one) proposal, it comes from another designer that has adapted the original icon, he's a macrumors userIt needs some adjustment because the designer worked on a low-res file.
Do you like it ? I like it !!
VERY nice!
