Not really. The menu item in VAssistX main menu is called "Insert VA Snippet". Same action can be triggered if I select some text and press Ctrl+Space hotkey
You can re-order the items in the menu. Simply go into VA's snippet editor and then drag and drop the items in the tree. The order in the tree is used to set the order in the menu that appears when you trigger the insert VA snippet command.
This is not the same as what you are asking for, but it does help if there are certain snippets you use all the time.
Selecting the previously used snippet by default is an interesting idea. I am just wondering how helpful this would be. I use the Insert VA Snippet a lot, but I am always selecting a different snippet, and I am used to moving down the list to select the one I want. By selecting the last one by default I would have to move up the list sometimes, and down other times.
Yes I'm using the re-ordering and I agree its a greate feature. My idea about last used snippet comes from MSVS Intellisense for C# which does remember property or method you've last used. I've just double-checked, MSVS 2008 doesn't do this for C++ so you guys can make some C++ developer lifes better by adding this feature.
