I guess I'm not the first one asking for this, but I'll ask anyway:

Could we please get a few more "standard" Lotro UI elements, like dropdown menus, those nice sliders used e.g. for the UI scaling, maybe tabs and integer input fields like we get when selecting stack size for items?

I'm well aware that we can implement all that ourselves, but I'm seriously getting tired that I spend much more time on writing a configuration panel for my plugin than writing its actual functionality.
Now other plugin authors already did most of it, but having each plugin include its own copy of code and graphics is neither pretty nor memory efficient, and I still need to review their code to find out if it really fits my needs.
