Generally, it is better to avoid moving options whose values are files or lists of files. For example, a cache file usually corresponds to a particular trace file, and moving a
to another trace file or the default section would not make sense, unless the intent is to reuse that cache file with a different trace. On the other hand, you can drag and drop color definitions from trace to trace or to default (the latter will define that color for all trace files, unless they provide their own definition). Moving group definitions, however, requires more attention, since group ids in one trace might not make sense in another. To solve such issues, you can examine and edit values.
