Paper vote is a good and traceable way of doing things with far less chance of interference than electronic. And it feels more connected to make you mark on a piece of paper and post that into a box.
Choice was reduced when they raised the deposit but it is still only
£500.
And a the long time period on a Thursday is still a good time. Plenty of opportunity to vote even with odd work patterns. My wife and I plan to get to go to vote together. And since many polling stations are in churches, Sunday voting wouldn't work.
Fining is not a good idea, what if you suddenly couldn't vote in some unexpected manner. People may feel disenfranchised but they need to get out and vote anyway. Support that minor party so they don't lose their deposit. I think it would be great fun if we had a parliament of independents.
