The app itself is good and does what is stated in the description pretty well. There are only a few things I would like to see in a future update: - Not only be able to select the base currency but also the 'fallback' currency. For example I would like to see all my coins in ETH but than ETH will be shown in $ and I can't select EUR for that. Even better would be to select the currency for each coin individually. - Only distributed via AppStore and I hate any AppStore and would never buy any software there. ATM its free so its acceptable but I would like to pay a small amount / buy a usefull tool. But I won't do that in any AppStore. Maybe you should offer this app for download on your webpage with a donate possibility (NO PayPal). Maybe ask to donate some ETH or JSEcoins as users of this app would have some of them :-) - Add a standalone window mode that could be displayed all the time instead of only menu bar. You can't use the menubar for more than a few coins and always having to click in the menu to open the list is a bit annoying. - More smaller coins like those traded on Latoken. Not sure if they offer an API but maybe there is an other source for that data. So if you just have 2-3 different (major) coins this app is great.
