I only noticed it because I was trying (via text messages) to help a friend who is new to using TVPaint and was asking about "using something similar to a Mask in Photoshop". I said: "It is not exactly the same as in Photoshop, but search the User Manual for stencil". He told me: "search results in the User Manual for 'stencil' does not make it clear how to do this" . So I did a search myself and discovered that the information he was seeking is categorized under "The Masks". (this was easy , because I remembered that "stencils" were at one time called "masks". But I thought that the terminology had been changed to "stencils" in the user manual , however it is not changed yet , so it becomes confusing for the new user to locate the relevant pages in the user manual).
I know that all of you at TVPaint have too many tasks to manage each day , but I am afraid the only solution I can think of is the tedious solution to assign someone to go through the User Manual slowly , page-by-page , to check for inconsistencies in terminology and update screenshots that do not match the current interface. (also to add certain new functions that have been added since the TVPaint 11 user manual was originally published). As it is , I usually discover these areas of the User Manual that need to be updated because I am helping someone who is a new user and when I search for the topic in the user manual I discover places where the manual is not updated.
