with the exception of the repel grenade, timed explosives should have some sort of indication of when they're going to blow up or how much longer they're active (like a timer or progress bar)
Not possible without reworking tons of existing items. Lots of items use the internal timer for various things, and exposing it via a progress bar would mostly just mess things up. For example, some of the staves continuously cycle the timer and use it to draw their particle effects, which would be quite pointless to display.
I'm experiencing frequent glitches where the game will lag like crazy and you can't do anything. When I try to pause, the blueprint and grid will not appear, and I can't move anything. Please fix, really annoying as I have to refresh the page often.
The whole aiming thing was added as a result of Blunt Power being added in the latest patch. I figured I might as well make it toggleable since it worked pretty well.
Open the console using the Home key, type in "fps" without quotes and press Enter. The counter will appear in the upper right corner of the screen. Click on the stage to unfocus and press Home again to close the console.
It uses the average velocity over a few frames now to make throwing easier (before it only checked a single velocity on mouse release, making it a bit wonky.) -- this also means that if you're shaking your cursor frantically, the velocity might average somewhere weird. Throw in straight lines and you should be fine.
