 // TODO: localize
 // TODO: wieso geht copy paste im twebbrowser nicht???
 // Wieso dauert webbrowser1 erste kompilierung so lange???
+// TODO: wieso kommt syntax fehler zweimal? einmal stderr einmal stdout?
+// TODO: Browser titlebar (link preview)
+// TODO: strg+f / h
+// TODO: font bigger
+// TODO: code in bildschirmmitte?
+// TODO: regelmäßig scrap zwischenspeichern, oder bei strg+s
 // Future ideas
 // - ToDo list
 // - Open/Save real files
 // - multiple scraps?
 // - verschiedene php versionen?
 // - webbrowser1 nur laden, wenn man den tab anwählt?
 // - doppelklick auf tab soll diesen schließen
