The journal icon does not show up in the frame until the indexing is
finished and no journal operations are possible. So, I guess, you also
cannot open activities.

Don't know, I'd have to measure with a full journal...

Even without testing I have a very strong feeling that automatic
reindexing on every boot won't be a feasible path. Perhaps we could
perform full reindexing every N boots, like fsck on old Linux systems?
Naa... users would be annoyed by the useless occasional delay and would
demand a button to fix their journal when they know that some data has
been lost.
