TYPO3 Core

It would be nice to have some additional TSUserConfig possibilities to configure the Typo3Browser plugin:
- Disable target selection for page/url type to avoid having links which are not xhtml-strict compliant. (Perhaps I could apply a filter to get rid of the target attribute but the editor would be confused that his settings were ignored).
- Disable the creation of a popup-window for page/file/url.
- Swap page/file tree and options (see attached image) because the window closes when you click a page or file and you'll have to open the link tool again to set the options. This way you could set the options first and then select the page/file.
