O5220803  CORRECTION: in Mail Plane select "Standard View" in GMail; then Select "Settings", THEN: "Open your Gmail settings and enable keyboard shortcuts"; it works correctly for the Mac version of MP. BTW, this solution was found through experimentation. MP should update their "Help" information to reflect this.  
(Version 2.1b)

CROUPIER49  Version 2.1b is a beta version. The developer's website clearly states the version is beta and notes there may be some bugs since it's still being tested. The site suggests you use the most stable released version (instead of the beta version) if you don't want to be part of testing or experience bugs. I use the most current released version (not this beta version) and have had ZERO problems. It's very handy and well-maintained. Yes, you can use a lot of free apps and browser add-ons to get similar (though not all) features as Mailplane, but they don't look or work as nicely.

HARRISTYPE  I completely agree. Finally a review that doesn't take cheap potshots at those who simply didn't like it. Every app under the sun has its supporters and detractors. I was an original beta tester, and unfortunately it wasn't for me. For what it did, I thought it was too expensive, but for others, I can see it be an invaluable app. The only reason I got involved with this discussion was because of the childish behavior of another reviewer and his insults just because some of us didn't like the app, or didn't agree with him. Kudos to the developer for his continued updates, and maybe someday, when it has the features I need, I'll take another look. It was never because I couldn't afford it.

ANONYMOUS  Thanks for your review!

One thing: Mailplane isn't based on Fluid or related to Fluid. Mailplane's executable file name needed to be renamed because of a Gmail video chat incompatibly.

CORPSECORPS  But $25 for software that makes use of a web mail service?

Plus Apple mail can use that storage space via POP3 or even IMAP for $0.

HARRISTYPE  I would consider myself a gmail power user, having 2 personal gmail addressess and 2 business gmail addresses. I was an original beta tester of Mailplane, and to me this program still falls short in several areas (like no access to Google calendars, at least when I last looked at it).

Right now, I'm using Firefox and a couple of add-ons, and gmail is working perfectly for me with all of these accounts, so shelling out $25 for a front-end to a free service is a waste of money.

PALADINO  It's not necessarily a matter of folks being unable to afford Mailplane. Many of us just don't like the idea of pissing away $25 on an overpriced trifle.  
(Version 2.0.2)

KILLER KLOWN KAR  Once again you fail to understand the concept of time/money. I'm sure you have plenty of the first and little of the second. I have Mailplane running on four Macs. One a dual quad is for production only. I don't even launch a browser on it, (well rarely) but I do need email. Tell me el - cheapo how do I check my 4 gmail accounts at the same time? Firefox for all it's improvements still has memory leaks galore, and gmail doesn't really format correctly in Safari. Of course I suppose for the financially disadvantaged that is perfectly acceptable.

I simply find the reviews here to be pathetic. No one is actually reviewing the product. Everyone is simply whining like little bitches about the perceived value. Mailplane is solid, well supported, does what it claims, saves me time and effort. So what value is that, $25? Seems a pretty good deal to me. So use your crashing free browsers and plug ins. Free is what you establish your value/need as.   
(Version 2.0.2)

MACSOLU  So, since you have this app installed on four Macs, you shelled out a total of ONE HUNDRED DOLLARS for four MailPlane licenses? You obviously have way more money to burn than most users, especially considering there's perfectly fine alternative methods to access/interact with gMail.  
(Version 2.0.2)

HARRISTYPE  Gee Killer Klown Kar, I'm sure the developer would love having you write testimonials for Mailplane. I can see it now: "I love Mailplane to death, and anyone who doesn't like it or doesn't use it is an "el-cheapo whining little bitch". Easy there, trigger!  
(Version 2.0.2)

HMURCHISON  Macsolu - Mailplane has a family pack for 39 bucks so it becomes a pretty good deal for someone with multiple Macs. I'm thinking about getting the family license because even for just three Macs it's 13 dollars and that's not half bad. There is value IMO in having more desktop app functionality.

RUSKIWI  How do you check 4 gmail accounts at the same time? Like I do, in either Apple Mail or M$ Entourage - both are email applications, not browsers, and work just fine for checking gmail.
