Recently I found myself using Save Selection / Load Selection feature quite a lot, while working with assistant who culls images remotely.
After doing the whole procedure for several times I found it takes 5 clicks save selection, and then 6 clicks to load it.
I think it can be done way faster if few things are implemented.
1. add shortcuts to save and load selection — faster to call the feature
2. keep the previous selection.txt file already selected in window — no need to choose the file every time on both save and load.
3. in line with points 1 & 2, make it work with option key, so that shortcut just saves selection to previously used txt file. And does the same with loading.
