First impressions, I have mixed feelings - one being it's cool and new, the other feeling that it's a bit clunky.

In my opinion Maple is starting to look like the interface is being modelled after Microsoft Office, or like the ribbon toolbars of AutoCad or Inventor.  Maple's "uniqueness" is disappearing.  I rather liked the old interface. 

The toolbar icons are larger, taking up more space.

The toolbar layout is indeed simpler, but also less efficient maybe.  I mean there were more useful available icons at once before, more functional is the word I guess.  Now it might be a couple of clicks away to pull up your favorite icon(s).  The icons all look very nice, that's a plus but they could be smaller.  

Perhaps we could make a customized menu toolbar?  That is, allow users to put all the most useful icons we use or would like the most to be displayed?  This would help some of the strange organization of some of the icons and allow us to make our maple "sandbox" feel more at home. 

The workbook includes the excel data file but I also included the worksheet and data file separate for versions that can't load workbooks.

This should be a rule. 

If replies and answers are deleted  then there must be a secondary acknowledgement from the original poster to do so.  The reply or answer can not be deleted under the response of another person and only the acknowledgment of the top poster / questioneer will that, answer/reply, be allowed to be deleted. 

Also goes with re-organizing the order of replies/answers - only happens if the person who started the thread acknowledges the action. 

Too many times have answers / replies been jumbled out of order.  Just because it makes sense for one person, doesn't mean it makes sense for everyone. 

edit added *** this is also to cure the mandella effect in this forum (or perhaps you just thought you were getting dementia) .... I swear someone answered this post but where did that answer go?  ******

The original app center was excellent, they were .. "finessed" so to speak.  Then they changed it (like so many websites today most are clunky and they're all terrible, they don't work well, and I'm not just singling out maplesoft)  Most websites that are finely tuned are most likely based on old school programming, just recall the old days of mapleprimes - the forum was nicely done - but that's a debate for later. Now to the nitty gritty.

I did a search at maplesoft app center of a particular author, and I know he has at least 20 applications.  Only 3 came up, and the last app entry said more apps by this author but it kept disappearing and I kept getting thrown back to application #1 all the meanwhile looking like I'm scrolling further down in the list. 

Maybe this is browser issue?  I'm using firefox.  Maybe Microsoft Edge works better?
