One of the things I hope to do with this blog is to make comments about what users are tweeting about for Live Writer. A topic from a few weeks back now was a topic about how to remove an entry from your custom dictionary once you have added it. This is one place where Live Writer does fall short. The Add menu item is there but we do not have the ability like you do in Microsoft Word to edit your list of words you have added. As the post points out this is just a text file that you can edit in any text editor like Notepad.
One thing I would note is to make sure you do not leave any gaps in the list and that you only have one word per line.
A great idea for a plug-in would be one what lets you first import from Word/Office so you have the same custom dictionary in both Office applications and Live Writer for spell checking and also just lets you edit the list without having to dig down into your application data folder and find the file you need to modify. I’ll add this to my todo list to work on some day. Leave a comment if you beat me to it.
