I can only speak for myself.
Most changes I do on Android, with QuickEdit+. I make edits on an extra file /_themes/Tapiola.xml, which I then copy (Totalcmd) into /_themes/Tapiola.zip/Tapiola/Tapiola.xml - then re-apply theme in Locus for testing.
On PC, far better overview, code folding etc. I use (MS Visual Studio) Codium. Sometimes PSPad. I copy the xml with Totalcmd/Android (accessing a Windows share) into the zip file.
No, no specific theme editor.
Yes. Every syntax error results in a blank display. Reminds me of my Perl job years ago. Syntax error results in http/500, internal server error.
