I have some (admittedly rather primitive) export/import functions coming in the next version. Basically you will be able to export all of Sidewise's settings and data to your clipboard, which you can then save to a text file. For the import side, you reverse the process (paste some previously exported data into a text box in Sidewise).

Longer term, I'll be looking at ways of exporting/importing that don't involve the clipboard, such as storing your data in a database that I host on http://sidewise.info. I also plan to do something along the lines of automatic periodic backups of your data, along with something like a drop-down list on the options page that lets you choose to restore everything to one of the saved "earlier versions" on demand.

Longer term, I'll be looking at ways of exporting/importing that don't involve the clipboard, such as storing your data in a database that I host on http://sidewise.info, and doing silent automatic backups of your data on a periodic basis ... and then basically adding a drop-down list to the options page that lets you restore to one of the "earlier versions" on demand.

Hmm ... what about making the pinned icon an "overlay icon" on top of the favicon?

Kinda like this: overlay example 

(A) This is tentatively planned but probably won't get completed for some time. 

(B) Styling support in general is planned, and I'm planning on at least a couple darker themes to come packaged with that: one that closely mimics Tree Style Tabs, and one that mimics this editor's lovely color scheme.

That's a cool idea, I'll look into it.

I believe all or most of these issues will be fixed for the next release. Thanks for the report!
