Multiplier for powertools, independent of XP and levelingSuggestion
I think allowing the gather multiplier to be applied when using powertools without zlevels applying XP points and leveling up would be a great idea. It would mean the users would have to work with handtools to level up and increase the gather multiplier, but then could reap the benefit while using powetools without powering through zlevels. It could be done with a config option to turn it on or off. Something like this:

//In levelHandler
...
var xpPercentBefore = getExperiencePercent(player, skill);
var Level = getLevel(player.userID, skill);
var Points = getPoints(player.userID, skill);
item.amount = Mathf.CeilToInt((float)(item.amount * getGathMult(Level, skill)));
if ( powerToolsOnlyGiveGathMult && ( player.GetHeldEntity() is Jackhammer || player.GetHeldEntity() is Chainsaw ) )
    return;
var pointsToGet = (int)pointsPerHitCurrent[skill];
var xpMultiplier = Convert.ToInt64(playerPrefs.PlayerInfo[player.userID].XPM);
Points += Convert.ToInt64(pointsToGet * (xpMultiplier / 100f));
getPointsLevel(Points, skill);
...​
And then powerToolsOnlyGiveGathMult would be your config variable.

I think this code would work, not sure though I don't have experience with Rust Plugins.

I would definitely like to see separate multiplier for the chainsaw and jackhammer, but I would rather not have it separated from XP or leveling as that complicates the user experience.

I think it would be easiest if you could set the percentage in which power tools use of the overall multipliers.

Maybe have another config setting that allows you to set the percentage of DefaultResourceMultiplier power tools use. For instance, have PowerToolResourceMultiplier. If you set it to .5 and DefaultResourceMultiplier is set to 2, then it's 1. 

Obviously, there are other solutions, but regardless, it would be nice if it was possible to allow these tools.

At the very least it would be good to set these off by default. Player rocket up levels when they're on.

To clarify why I'd really love to see a separate multiplier for the power tools, I had to disable the Jackhammer and Chainsaw cause players were leveling up like crazy. It would be great to be able to set their leveling multipliers separately so they could be included in zlevels.

I second this suggestion though it looks like this plugin is dead (support wise)

I too had to disable the power tools, which sucks because people love them, because the level gain was just dumb
I'm doubtful it's dead. It's a top plugin here at uMod. Typically @FuJiCuRa is responsive. I'm sure he's just busy with something.

I would love this option! Are there any news? My players are asking... :) 

I'm glad I ran across this one. Did anyone manage to get this worked out?

no unfortunately not..

This is a cool idea would love to see it working. top vote lol

Would it be possible to add a setting that let the admins slow down level progression when using the jackhammer and the chainsaw? I can go up one mining level with 3 nodes. I love the fact that these skills can be increased with these items but I think the progression should be a little slower.

I guess the plugin author has no time for such things :(
