I would like to be able to customize highlights in a way that I have separately selected background color and foreground colors. Is there a way to do that. Here is an example from Baretail log viewer that I am currently using:

Hi Djordje,

Just a quick update on this.  We have just released LogViewPlus v2.5.22 which includes a new Rules feature which I think might help with this scenario.

One of the rule actions allows you to set a foreground and background color.  So, what you can do is create a filter which finds the records and then create a rule on the filter which applies the appropriate coloring.  You can then hide the filter by deselecting the 'show filter' checkbox in the rule properties. 

Once you get this setup, you can save the rule either as a template or an automatic template.

Hope that helps,

Toby
