Hey, I'm quite new and wanted to share a few ideas.
I see there are already threads about how to make the rune system better. My suggestion is about the UI itself.
1-) Tidy rune list
Current situation: I'm not sure how it works since we get runes en masse.
Suggestion: Make it auto-sorted with every rune movement (in or out). Two characteristics should be enough for sorting. Greater priority is on rune power (lesser/normal/greater), second priority criteria is name. It's also possible to include a button or two to change the sorting priority. In that case, name would effectively refer to the type.
Example: I have Greater Rune of Furor, Greater Rune of Alacrity, Rune of Furor. If I sort them with "power" as high priority in ascending order, they will be sorted like: RoF, GRoA, GRoF. If I sort with "name" as high priority in ascending order, they'll be sorted like: GRoA, RoF, GRoF.
Even without buttons, a simple alphabetical sorting would make rune browsing so much easier.
2-) Getting runes into/out of stack
Current situation: You need to drag runes onto the book, out of the book, on the combiner, out of combiner.
Suggestion: Make a shortcut like double-click or ctrl/shift/alt click to move runes between the list and active tab. Also include a "clear runes" button on runebook (if we dont have it) and combiner. You can even include a shortcut to place runes of same kind.
Also make them swappable. That is, if i drop a rune from stack on a rune on the book, get the one on the book to stack and the one from stack to that slot. (thanks to spunkify)
Example: I have 3 Seals of Malice and 2 Seals of Furor. If I double-click on Seal of Malice, it directly gets placed in my first empty seal slot. If I ctrl+double-click on Seal of Furor, both of my seal of furors get placed into my free seal slots (as long as there is space)
I'm pretty sure people will like to experiment on various runes and these will make rune-switching much less tedious.
3-) [Beta] Rune choosing and/or deleting
I doubt anyone will want to delete runes but for beta we could really use one of these. It's quite annoying to cross your fingers to get the runes you want when you want to try something. So if we can choose the runes we get, or we can clear unused runes (so that rune limit isnt full) it'd be quite easy. Currently we have to combine all unused runes.. which usually leads to more unused runes.
That will be all.
