NTT automatically overrides manual screenshot

[eberhardweber]

Cross-referencing issue #359, whenever I manually replace a half-baked tile screenshot that NTT takes automatically, it gets overwritten by an automatic screenshot sooner rather than later.

Is there a timer for the screenshots? Would it be possible not to override manual screenshots, or perhaps introduce a setting that would prevent automatic screenshots for manually set tiles?

When you edit the tile on the new tab page, you can click "save current thumbnail". That will prevent it being overwritten.
