If you are running a version of Windows before Windows 10 and when downloading/updating get a message similar to, "Could not create SSL/TLS secure channel."... please install a newer version of the .NET Framework from Microsoft. Vista can only use v4.6. Others should install the newest available, like v4.8.
Custom trigger tab suggestion
The recent change to be able to remove an entire category of custom triggers got me thinking.
Being a borderline hoarder, I hate to lose triggers, even if I'm not using them anymore. How about if ACT could remember if I collapsed a category? Then I could collapse those that I'm not using anymore so they only show one line for the category, but still retain the triggers. Adding or removing a trigger or exiting and re-running ACT would remember / restore each category's collapsed / expanded state.
