The presets function in Actions is extremely useful... Switching between groups of Actions essential to my workflow. But, frequently manipulating the preset menu takes a lot of extra clicks. There is also the opportunity for error should you do a quick Alt-6 and hit Enter, forgetting that the Action dialog will be on the last preset that you used.
I think the idea of Action presets can be made even more useful if we had an additional way to quickly invoke them that was exposed at a high level in the GUI, and did not have any kind of memory for the last preset used. Imagine a new button panel, set of toolbar buttons, context submenu, or even hotkeys -- one for each Action preset. Make that selection, and that preset is executed -- that's it.
This would save a lot of keystrokes and mouse clicks needed to switch presets, and eliminate the opportunity to make a careless mistake by running the wrong preset due to the way the previous preset is remembered in the Action panel.
I'm not suggesting changing the Action panel or preset function at all, just adding a new instant way to execute the presets defined therein.
I've always wondered if and why users should use these presets. My "presets" instead are action groups that I have defined for my workflow and the compilation of individual actions is reliably constant. To be honest, I would never think of clicking together actions that I would have to check the ticks every time I executed them in order not to cause any harm.
That's natural. But do you combine with ticking several action groups? If have defined more than 40 single actions and action groups, partly grouped in the menue with naming (using #). If a want to execute an action I click on Actions or the little arrow at the action icon and select my action to execute.
Scrolling is not necessary here because of grouping with #. Anyway they fill nearly the whole screen but I use only the first 10 entries regularly because I have arranged them in the order of most used. That I have to look a little bit closer to select a seldom used action does not bother me.
