just a very minor glitch I noticed while with the software, here are the steps to reproduce:
- start a new DF
- create a new layer under ROOT
- rename it to "FOO"
- now create another layer under ROOT
- new layer appears (named DEFAULT)
- new layer tab also appears, also named DEFAULT
- now rename the layer to "BAR"
- the new tab remains named DEFAULT, only the treeview is updated properly
