To think the eBay site needs an overhaul?

[brinkdrop]

It's very ugly to look at, and there are so many irritating things about it.

One of the recent glitches is that it no longer shows you how far away an item is, also it doesn't show you your message chain when you open a message in your inbox.

Yes! Infuriating isn't it? Great idea. Needs an update... I rarely use it now.

Yeah, there are more accessible and modern selling platforms these days. It needs to up its game.

All I want is for it to have a setting which shows me UK results only, as the default, not me having to click it through the menu every single time I search.

Agree ebay is clunky and ugly, but on the other hand you can search in quite sophisticated ways and set up alerts. Vinted on the other hand is fun partly because you can't search with much precision and can stumble upon a bargain others haven't.
BTW If losing bids on ebay at the last moment frustrates you I recommend Gixen sniping tool. It may look amateurish and dodgy but is actually great and I've been using it with confidence for years.
