I want to use my Metamask wallet on a different pc so I installed the chrome plugin and entered the words seed. The balance shown seems to be correct, but I cannot find a history of my previous transactions... Anyway to show this in the new metamask wallet?
I don't think it will look up previous transactions in the chain. Afacit the only way to do that is by looping over the blocks and I can't see any code that does that.
edit: my comment is substantiated by the issue that Nicolas linked above: https://github.com/MetaMask/metamask-plugin/issues/505 MetaMask does not implement this functionality (although other wallets might).
etherscan.io is a very useful tool, you can find every tx history there.
