Firstly I've been really impressed with Logomaker and I recently cracked 100 sales so I'm definitely making progress but here are some of the things I would love to see:
Client Facing:
The ability for a buyer to choose how many designs come up when they click go e.g. 10, 20, 30 etc. Really important when someone is viewing with poor connectivity
The ability for the buyer to scroll for more designs by clicking a button or sliding scale for 'Brand Personality' or 'Style' - currently it takes a lot of clicks to search again....
Better additional suggestions for the buyer based on Similar industries/ Similar Styles/Similar words etc
Some better education elements - simple slides showing buyers what you mean by 'Brand Personality' with examples as I think this is one of the most confusing selection option
Designer Facing
The option to make bulk changes to logos - e.g. you select 10 logos and you see their industries/ styles/ personality on one page and can edit those elements and then save the whole amount
The ability to see Data for clients interactions with each logo - How Many Impressions / Most popular keyword that it appears under / How many clients attempted to edit / how many logos are Abandoned Carts / which industries are performing best for a designer - I feel this kind of info is crucial in order to understand why some logos are/aren't performing
Designer Interface
The ability to reflect a logo left/right or up/down - this would be great for when I'm creating alternates that are really different and not just colour changes (that the interface already offers)
Add the option of at least one gradient colour per design - simple 2 boxes of colour with a sliding scale for the gradient (including 'alpha')
Add some more shapes on top of Square and Ellipse (Triangle, Pentagon, maybe even star)#
Examples of Brand personality (see client suggestions)
There have been a couple of mentions of fonts - the current font allocation system is pretty bulky and cumbersome - last used or favourites would be a definite plus!
Finally the ability to replace an exiting design with a new version and keep all the metadata/history of the original (just term it v2) why is that important? Well because designers get better - one of my most popular designs is one of my earliest however it's incredibly cumbersome in terms of how I created the SVG - I am sure the sales would improve if I made it easier for buyers to create alternate versions however I don't want to delete it as it's doing so well.
That's everything - I hope that these suggestions are useful, I really enjoy Logomaker so keep up the good work!
