<br>
Great idea!<br>
<br>
Something that springs to mind though, I think you can only control this behaviour once you've opened an attribute table currently? Would you also be looking to add another way to control it? E.g. in the layer menu or on right clicking on a layer in the layers
panel.<br>

Subject: [Qgis-user] Changing behaviour of "show selected features" mode for attribute table<br>
<br>
Hi all,<br>
<br>
I'd like to raise discussion about changing the behaviour of the "show selected features" mode in the attribute table.<br>
<br>
Over the last couple of weeks I've pushed fixes to both 3.0 and<br>
(shortly) 2.18 to improve the performance of the attribute table when this mode is selected (Thanks to Faunalia and ENEL for sponsoring this!). With these changes *only* the selected features are fetched from providers to show in the attribute table, vs the
current behaviour of fetching *everything* and then filtering out to the selection. It makes a huge difference for working with large layers.<br>
<br>
Now - there's one last piece of this I'd like to land, but it changes the behaviour of this mode. Currently if you have the table set to "show selected features", but there's nothing selected, then ALL features are shown.<br>
<br>
This kills the benefit of setting the table to show in this mode. If you accidentally open the table for a large layer with no selection, it'll force every feature to be fetched again.<br>
<br>
I'd like to change this, so that no selection = nothing shows in the table. This means that users can safely set the attribute table to always show in "selected features" mode and be confident that they'll never hit the situation where every feature is fetched
(unless of course they have selected *every* feature!).<br>
<br>
Does anyone object to this change landing for 3.0 and 2.18?<br>
<br>
Nyall<br>
