Two things I could use some help with...
Is there a simple Find-\>Replace option that doesn't depend on using regex? Let's say for instance that every title ends with " (Instrumental)" and I want to remove that from every title, including the leading space. Is there an easy way to do that?
Unrelated, when using the Tag - Filename conversion I'm wondering if there's a way to conform the padding of the track numbers so they're all the same number of characters. So if I had an album that was 5 total tracks and used the Tag - Filename conversion with %track% %title%, the resulting filenames would look like:
1 Track One
2 Track Two
3 Track Three
But if I had an album that had 12 total tracks, now we pad those initial tracks with a leading 0, such that:
01 Track One
02 Track Two
...
11 Track Eleven
12 Track Twelve
And if I had a really long album with over 100 tracks, we'd need even more padding, such that:
001 Track One
002 Track Two
...
101 Track One Hundred One
102 Track One Hundred Two
Hopefully what I'm asking makes sense. Thanks for the help!

I can help with no. 2:
If you have `%totaltracks%` present in your file(s), you can use
> $num(%track%,$len(%totaltracks%)) %title%
This reads: pad `%track%` with leading zeroes, until digit count matches that of `%totaltracks%`; and `%title%`
You can also find a list of available functions here:
> **[Scripting Functions – Mp3tag Documentation](https://docs.mp3tag.de/scripting/)**

Hope this helps.

Create an action of the type "Replace" for TITLE
Original: (Instrumental)
Replace with:
(leave empty)
More about actions, see the documentation:
