@ -3,11 +3,15 @@ fw-daemon:
remove all stale references to SANDBOX: rules/policyForPathAndSandbox()
TLSGuard needs a lot of stuff removed
fw-prompt:
scope returned by new rules is bad (always set to process)
apply once rules still do not work because they the DBus invocation requires the guid to be passed
remove duplicate code for creating new treeview items
Each duplicate prompt needs to be expandable into individual items
more nesting for similar prompts (by application, pid, target host, etc)
