Snippet Explorer filtering not working as expected

[OJacot-Descombes]

1. When I open the explorer, the snippets list is empty. I would expect it to show the snippets of all the checked languages without having to click Search first.
2. When the languages C# and VB are checked and I click Search with an empty search box, I would expect all the C# and VB snippets to be listed; however only the VB snippets appear. I have to uncheck VB and to click Search to see the C# code snippets. Note: this happens because the display limit of 25 is selected by default. This is very disturbing the first time you are using the SnippetDesigner. The maximum or no limit should be selected by default.
3. The filter should be applied automatically after a language is checked or unchecked, without having to click Search. Clicking Search should only be necessary after editing the search text box.
4. When the search text box is empty, only built in Visual Studio snippets are listed. I have to enter a search text to display my own snippets. This is because of the maximum as selected in the Show box is reached. Filtering is very fast. Do we really need this display limit? At least we should have the option to select "no limit" or the maximum limit (1000) should be the default. It would also be cool to have a check box "Only My Code Snippets".
