Despite spending all my time developing Domino browser applications, I still make a point of giving them nice icons, quite early on in the process. Whether or not you agree they are important they can still be quite useful. Personally, I don't use Bookmarks at all and still rely on the good old Workspace. Here, icons come in really handy.
We all know how to change the icon, but making your own is only for the brave or the artistically gifted. I tried once and never have since. Here's how I do it now:
Get yourself a copy of an image viewer that will show you the images contained inside .ico and .dll files. My favourite is Multimedia Explorer, which is now freeware. If you browse folders likes Windows\System for DLLs you will soon see what treasures are contained within some, like below:
When you find one you like, select it and use the Copy Image command from the Edit menu to copy it. Now open the Notes icon for editing in the client and use the Paste button to include the new image. Colour depth and size should match ok, as below:
You can make them even nicer though! Open the icon for editing again and select the same two tools from the left-hand side as I'm using below:
With this tool combination (the eraser end of the pencil and the spray tool), click inside the white areas one by one until they all become transparent. You will then have an icon that looks much more professional, like so:
There are lots of files you can look in for great quality icons. Try some executables as well. The Office programs have some nice ones. As does Outlook and its Express sibling. Happy hunting...
