1) You mean just an empty no-function name?
2)I'll do more functionality updates in extensions going forward, the core is already very sizeable and filled with features to the point it can become clustered.
3) Noted.
4) Unfortunately, and not because it is impossible, I won't be disabling this. Most I would do is paint the name color red or something but no removing from the selection, least not just yet. May make it a map configuration option going forward however so it is noted
5) That's disruptive to function and can force start a battle when the player is not sure. That is the rationale why it doesn't popup immediately and why the battle starts automatically when all actors are auto placed
6) For skill names and item names, the database itself. For window names such as the text for selecting a battler, you can go into a text editor and just change the text from there. The plugin is not obfuscated and having too many parameters in the plugin manager can lead to clutter
