I wish you could donate more money to poor people than 1 septim sure its a noble undertaking if you have 100 but when you have say 100,000 it seems more like spitting in their unwashed faces. Also be really nice if you could say get a beggar back on his feet....so to speak.
I've spent thousands on Silda the Unseen for pickpocket training, yet every time she starts begging for a single septim, which I then give her. For that she's overjoyed. At least she left me 100g in her will.
