I find myself unable to set up layer masks in the inspector because it is not showing what layers are currently selected: I think on Windows, there are little check marks next to the selected items. This may be due to unicode problems: I have nodes in my project tree that have unicode symbols in their names which are also not showing on Linux. My desktop environment uses the Noto Sans font which should include the necessary characters and symbols (assuming the GTK2 context menus use the default font).
This is a known issue with the gtk menus - we're currently not marking any of them as checkable, due to silly implementation details.
I would be happy to have a least something, even if it's just a star or plus sign in front of selected lines if there's an issue with checkboxes
The issue isn't actually rendering the checkboxes (gtk has a checkable menu item widget built in), it's that gtk handles them differently than windows or mac, and we haven't worked through unifying the behavior yet.
Okay thanks for the explanation It just looked like someone already went through the effort to toggle the layer bits when an entry in the context menu is clicked - even without checkboxes. 'would have been cool if that included a simple marker in front of selected layers.
