We've had a lot of people request a custom icons feature in the past. People want to add their own icons to the app and have them appear when placing icons on the canvas.
With Mims Wright stepping in for some Mockups development, we've added this feature to the pre-release version of Mockups and are looking for some users to give it a try. We've updated the Icons Documentation to reflect this coming change.
Note: This feature is only available in pre-release version at the moment, and requires you that you use the pre-release to test this out.
Now when you add an icon, you'll see 2 new tabs for Account Assets and Project Assets (if you're working on a saved file).
If you select one of the tabs, you'll see an Add (+) icon. Click it and an image dialog will open so you can add icons individually.
Now when you add an icon, you'll see your custom icons in the tab you've added them to.
There's a method for power-users who want to front-load the app with all of their custom icons, by saving filenames starting with icon_ to either the account assets or project assets folders.
I did this on my Mac by downloading the free 32x32px Doodlekit icons, ran them through the free NameChanger app to prepend files with icon_, and moved them to my Balsamiq Mockups/assets folder. They now appear in my icon dialog like this:
The words you use in your filename after icon_ are used as the searchable keywords in the icon dialog. So the example above shows airplane because the filename is icon_airplane.png. You can string together a few labels to get synonyms in there, e.g. if the file is named icon_bag briefcase portfolio.png, all of those words after icon_ will be searchable.
We're looking for your feedback and any bug reports. Play with it and let us know what you think.
