Incomplete product
Comparison takes far too long... a folder with ~1K folders/files on the latest version MacBook Pro 15" Retina i7 2.7GHz Quad Core, 16GB RAM, 500GB SSD takes nearly 60 seconds... thats the best part. Now I have a good comparison showing what is missing on each side - this is where it gets useless: you can only select one item at a time: NO MULTI-SELECT so you have to click one item at a time, right click then choose "copy to the right" or "copy to the left", then after a few seconds a pop-up appears asking if you want to re-compare, click NO then select the next item, wash, rinse, repeat as many times as you have files that need to be copied to the other folder. Hopefully you dont have more than a few. There is no way to disable the pop-up or select multiple files or folders that I can figure out.
Yes, I have synch apps that could handle this, but sometimes I dont want everything syncd just some items and/or I dont feel like setting up a synch just for an occasional comparison. The description says something about "if you have filemerge installed"- cant search while writing this to see if that means Id have to buy something else.
These seem like such obvious features there must be a reason why not included - being an engineer I get why youd want to diff files/folders, but the majority of the time there is additonal action you want to take once getting the results and its certainly shouldnt be so painful that you decide to write your first review of a mac app because of the easily preventable frustration... multi-select and get rid of the re-compare? pop-up after each copy.
Right now in the app store it shows "sale price" of $4.99 - I dont remember what I paid for this, but if it was more, it certainly wasnt worth it - its not worth five bucks. If comparison speed was improved and the multi-select was an option, it might be worth it. Id certainly change my review and update my star rating but since Ive never seen this app updated (looks like Aug 2012 was the last update) dont hold your breath.
