Hi Frank, thank you for the excellent feedback! I have been hard at work on FileSeek 1.8, and I am incorporating many of your suggestions.
Here are my responses to your points:
1. This is coming in version 1.8.
2. You can do this already. Just type the wildcard you want, like *jon*, check off "use regex" and it will search using those wildcards.
3. I think Windows 7 uses a different control for this, this won't be included in version 1.8.
4. This is coming in version 1.8.
5. Double-clicked results open using the user-configured application by default now.
6. This is coming in version 1.8.
7. This is more complicated. In order to add an icon I would need to create a shell handler DLL that Explorer would host in it's own process. This opens up the possibility for possibly Explorer crashes/issues, so I won't be adding this. I don't think the icon is worth the potential performance/stability trade-offs.
8. This is coming in version 1.8.
You can see the progress so far in the official change log here:
