Code Issues Pull Requests Packages Projects Releases Wiki Activity

* Add FileBaseFilters 

* Add HTTP(S) file web server with temp URLs
* Get temp web d/l from file list
* Add File area filter editor (all file area stuff will be rename to file "base" later)
* Concept of "listening servers" vs "login servers"
* Ability to get servers by their package name
* New MCI: %FN: File Base active filter name
* Some ES6 updates
* VC resetInitialFocus() to set focus to explicit/detected initial focus field
* Limit what is dumped out when logging form data
