1 problem: after a restart of Geany one need always to click 2x the spellcheck-symbol FOR EACH document that appears automatically with a restart of Geany to see the errors although the spellcheck-symbol is activated in the symbol-bar
possible solution: check session files on startup, when "spellcheck on/off"-symbol is activated
2 instead of a "spellcheck while typing"-symbol in the tool-bar: "spellcheck on/off"-symbol in the tool-bar (that should work exactly like "Automatic Spell Checking" in LibreOffice 7.1.3.2, what works in LibreOffice with the shortcut shift+F7)
