Mark thumbnails as annotated

[tschoeni]

Provide some visual clue in the thumbnail overview that an image has been annotated (full image annotations as well as marker-based annotations). This might be a toggle-able feature if the GUI should not be too cluttered on startup (or maybe an option a user can set in his/her preferences).

You can switch between flagging and actual filtering in the filter tab. This can be used to flag all annotated images:

The filter settings are remembered for each volume so you can reload the page an still see the flagged images. The filtering is not yet refreshed between reloads, though.

Aha! Missed that button. Which adds the question: does it make sense to group it with the filter icon or could it be placed somewhere else / separate of the filtering as it does something different?!

[mzur]

Both functions basically do the same thing only with a different visualization. Having two separate sidebar tabs that look exactly the same and allowing users to mix filtering and flagging of images has the potential to be highly confusing for the users, imo.

But why do you want to flag annotated images in the first place? Wouldn't it be much easier (in most cases) to simply use the filtering to display only images with(out) annotations?

Another case of RTFM. Sorry. Your features are even more elaborate than i expected (i thought flags are only to show annotations not filter results). But again, i did not get it on the first try so maybe it might be worth a redesign? Maybe set a default "filter" that flags all images with annotations? Then the users would immediately see an example for a filter?!

Another case of RTFM.

Well, we don't have a manual entry for the filtering yet, so it's not really your fault. I've created an issue for that.

Maybe set a default "filter" that flags all images with annotations?

I wouldn't go as far as setting a filter by default for these reasons:

• It would require flagging of images to be default. But I'd rather stay with filtering as default, since it is more useful.
• Each new filter rule sends an additional request. So if we set "has annotations or image labels" as default, we send and have to wait for two additional requests until the volume overview finished loading. That's bad UX.

But what do you think of this: We could offer filter presets like "has annotations or image labels" or "has no annotations of user {own user}". Users then could apply multiple filter rules with a single click.

Speed is important (actually thats whats keeping most of the users from using DIAS and BIIGLE from remote places - hence BIIGLE OTS might also lead to people using it on-shore!). Filter presets sound like a reasonable - one-click - alternative.
